Donna purchased office equipment and furniture for $13,220. She made a 20% down payment and financed the remaining balance with a 36-month installment loan at an annual percentage rate (APR) of 6%.

The down payment made by Donna is 20% of the total purchase price, which can be calculated as $13,220 multiplied by 0.20, resulting in $2,644. This amount is subtracted from the total purchase price to determine the financed balance, which is $13,220 minus $2,644, equaling $10,576.

To determine the monthly installment payments, we need to consider the APR of 6% and the loan term of 36 months. First, the annual interest rate needs to be calculated. The APR of 6% is divided by 100 to convert it to a decimal, resulting in 0.06. The monthly interest rate is then found by dividing the annual interest rate by 12 (the number of months in a year), which is 0.06 divided by 12, equaling 0.005.

Next, the monthly payment can be calculated using the formula for an installment loan:

Monthly Payment = (Loan Amount x Monthly Interest Rate) / [tex](1 - (1 + Monthly Interest Rate) ^ {-Loan Term})[/tex]

Plugging in the values, we have:

Monthly Payment = ($10,576 x 0.005) / [tex](1 - (1 + 0.005) ^ {-36})[/tex]

After evaluating the formula, the monthly payment is approximately $309.45.

Therefore, Donna's monthly installment payment for the office equipment and furniture is $309.45 for a duration of 36 months.

We have shown that every string in S contains an odd number of "a's".

The base case is straightforward since the string "a" contains exactly one "a", which is an odd number.

For the inductive step, we assume that every string σ in S with fewer than k letters (k ≥ 1) contains an odd number of "a's". Then we consider two cases:

Case 1: We construct a new string σ' by appending "a" to σ. Since σ ∈ S, we know that it contains an odd number of "a's". Thus, σ' contains an even number of "a's". But then, by the rule that −σσσ∈S for any σ∈S, we have that −σ'σ'σ' is also in S. This string has an odd number of "a's": it contains one more "a" than σ', which is even, and hence its total number of "a's" is odd.

Case 2: We construct a new string σ' by appending "aaa" to σ. By the inductive hypothesis, we know that σ contains an odd number of "a's". Then, σ' contains three more "a's" than σ does, so it has an odd number of "a's" as well.

Therefore, by induction, we have shown that every string in S contains an odd number of "a's".

The equation for the parabola with its vertex at the origin and a focus at (0, -1/4) is y = -4[tex]x^{2}[/tex].

A parabola with its vertex at the origin and a focus at (0, -1/4) has a vertical axis of symmetry. Since the vertex is at the origin, the equation for the parabola can be written in the form y = a[tex]x^{2}[/tex].

To find the value of 'a,' we need to determine the distance from the vertex to the focus, which is the same as the distance from the vertex to the directrix. In this case, the distance from the origin (vertex) to the focus is 1/4.

The distance from the vertex to the directrix can be found using the formula d = 1/(4a), where 'd' is the distance and 'a' is the coefficient in the equation. In this case, d = 1/4 and a is what we're trying to find.

Substituting these values into the formula, we have 1/4 = 1/(4a). Solving for 'a,' we get a = 1.

Therefore, the equation for the parabola is y = -4[tex]x^{2}[/tex], where 'a' represents the coefficient, and the negative sign indicates that the parabola opens downward.

The probability that eight out of seventeen random receipts will show the order of the Whopper, French fries, and a drink, given that 67% of customers order these items, is approximately 0.09108.

Let's assume that the probability of a customer ordering the Whopper, French fries, and a drink is p = 0.67. Since each receipt is an independent event, we can use the binomial distribution to calculate the probability of obtaining eight successes (receipts showing the order of all three items) out of seventeen trials (receipts).

Using the binomial probability formula, the probability of getting exactly k successes in n trials is given by P(X = k) = C(n, k) * p^k * (1 - p)^(n - k), where C(n, k) represents the number of combinations.

In this case, we need to calculate P(X = 8) using n = 17, k = 8, and p = 0.67. Plugging these values into the formula, we can evaluate the probability. The result is approximately 0.09108, rounded to five decimal places.

Therefore, the probability that eight out of seventeen receipts will show the order of the Whopper, French fries, and a drink, based on a 67% ordering rate, is approximately 0.09108.

We are to find the average slope of this function and find the value of c in the given interval such that ƒ'(c) = average slope of ƒ(x) in [-6, 8].  So, the value of c in the interval [-6, 8] such that ƒ'(c) = average slope of ƒ(x) in [-6, 8] is 1.

We know that the average slope of ƒ(x) in the interval [a, b] is given by: the average slope of ƒ(x) in [a, b] = ƒ(b) - ƒ(a) / (b - a). Let's calculate the average slope of the given function in [-6, 8]:

ƒ(-6) = 1 - 5(-6)²= 1 - 5(36)= -179ƒ(8) = 1 - 5(8)²= 1 - 5(64)= -319

the average slope of ƒ(x) in [-6, 8]= ƒ(8) - ƒ(-6) / (8 - (-6))= (-319) - (-179) / (8 + 6)= -140 / 14= -10

Thus, the average slope of the function on this interval is -10. By the mean value theorem, we know there exists a e in the open interval (-6, 8) such that ƒ'(c) is equal to this mean slope.

To find c, we need to find the derivative of ƒ(x):ƒ(x) = 1 - 5x²ƒ'(x) = -10xƒ'(c) = -10, since the average slope of ƒ(x) in [-6, 8] is -10.-10 = ƒ'(c) = -10c ⇒ c = 1. Therefore, c = 1. Hence, the value of c in the interval [-6, 8] such that ƒ'(c) = average slope of ƒ(x) in [-6, 8] is 1.

To prove the inequality |p|-|q| ≤ |p-q| ≤ |p| + |q| for points p and q in Rⁿ, we'll use the triangle inequality and properties of absolute values.

Starting with the left side of the inequality, |p|-|q| ≤ |p-q|, we can use the triangle inequality: |p| = |(p-q)+q| ≤ |p-q| + |q|. Rearranging this equation, we have |p|-|q| ≤ |p-q|, which proves the left side of the inequality.

Moving on to the right side of the inequality, |p-q| ≤ |p| + |q|, we'll use the reverse triangle inequality: |a-b| ≥ |a| - |b|. Applying this to the right side of the inequality, we have |p-q| ≥ |p| - |q|, which implies |p-q| ≤ |p| + |q|.

Combining both parts, we have proved the inequality: |p|-|q| ≤ |p-q| ≤ |p| + |q|.

0 ≤ x ≤ 3 - (3/2)y (from the equation of the plane, solving for x)

0 ≤ y ≤ 2 (from the limits of the triangle in the xy-plane)

For each (x,y) pair in the triangular region, the limits of integration for z are given by the equation of the plane:

For relation R = {(a, a), (a, c), (b, d), (c, a), (c, c), (d, b)} - R is not reflexive.

- R is not irreflexive.- R is symmetric.- R is not antisymmetric.

- R is transitive.

Let's analyze each of the properties of a relation for the given relation R on set A = {a, b, c, d}:

1. Reflexive:

A relation R is reflexive if every element of the set A is related to itself. In other words, for every element x in A, the pair (x, x) should be in R.

For R = {(a, a), (a, c), (b, d), (c, a), (c, c), (d, b)}, we can see that (a, a), (c, c), and (d, d) are present in R, which means R is reflexive for the elements a, c, and d. However, (b, b) is not present in R. Therefore, R is not reflexive.

2. Irreflexive:

A relation R is irreflexive if no element of the set A is related to itself. In other words, for every element x in A, the pair (x, x) should not be in R.

Since (a, a), (c, c), and (d, d) are present in R, it is clear that R is not irreflexive. Therefore, R does not satisfy the property of being irreflexive.

3. Symmetric:

A relation R is symmetric if for every pair (x, y) in R, the pair (y, x) is also in R.

In R = {(a, a), (a, c), (b, d), (c, a), (c, c), (d, b)}, we can see that (a, c) is present in R, but (c, a) is also present. Similarly, (d, b) is present, but (b, d) is also present. Therefore, R is symmetric.

4. Antisymmetric:

A relation R is antisymmetric if for every pair (x, y) in R, where x is not equal to y, if (x, y) is in R, then (y, x) is not in R.

In R = {(a, a), (a, c), (b, d), (c, a), (c, c), (d, b)}, we can see that (a, c) is present, but (c, a) is also present. Since a ≠ c, this violates the antisymmetric property. Hence, R is not antisymmetric.

5. Transitive:

A relation R is transitive if for every three elements x, y, and z in A, if (x, y) is in R and (y, z) is in R, then (x, z) must also be in R.

Let's check for transitivity in R:

- (a, a) is present, but there are no other pairs involving a, so it satisfies the transitive property.

- (a, c) is present, and (c, a) is present, but (a, a) is also present, so it satisfies the transitive property.

- (b, d) is present, and (d, b) is present, but there are no other pairs involving b or d, so it satisfies the transitive property.

- (c, a) is present, and (a, a) is present, but (c, c) is also present, so it satisfies the transitive property.

- (c, c) is present, and (c, c) is present, so it satisfies the transitive property.

- (d, b) is present, and (b, d) is present, but (d, d) is also

present, so it satisfies the transitive property.

Since all pairs in R satisfy the transitive property, R is transitive.

In summary:

- R is not reflexive.

- R is not irreflexive.

- R is symmetric.

- R is not antisymmetric.

- R is transitive.

The volume of Prism 2 is 360 cm³ by using the ratio of corresponding side length of two similar prism.

Given that Prism I has a volume of 30 cm³ and the two prisms are similar, we need to find the volume of Prism 2.

We can use the ratio of the corresponding side lengths to find the volume ratio of the two prisms.

Here’s how:Volume of a prism = Base area × Height Since the two prisms are similar, the ratio of the corresponding sides is the same.

That is,Prism 2 height ÷ Prism I height = Prism 2 base length ÷ Prism I base length From the figure, we can see that Prism I has a height of 6 cm and a base length of 12 cm.

We can use these values to find the height and base length of Prism 2.

The ratio of the side lengths is:

Prism 2 height ÷ 6 = Prism 2 base length ÷ 12

Cross-multiplying gives:

Prism 2 height = 2 × 6

Prism 2 height= 12 cm

Prism 2 base length = 2 × 12

Prism 2 base length= 24 cm

Now that we have the corresponding side lengths, we can find the volume ratio of the two prisms:

Prism 2 volume ÷ Prism I volume = (Prism 2 base area × Prism 2 height) ÷ (Prism I base area × Prism I height) Prism I volume is given as 30 cm³.

Prism I base area = 12 × 12

= 144 cm²

Prism 2 base area = 24 × 24

= 576 cm² Plugging these values into the above equation gives:

Prism 2 volume ÷ 30 = (576 × 12) ÷ (144 × 6)

Prism 2 volume ÷ 30 = 12

Prism 2 volume = 12 × 30

Prism 2 volume = 360 cm³.

The actual modeling of COVID cases involves complex factors and considerations beyond a simple cosine function, such as data analysis, epidemiological factors, and public health measures.

1. To prove the given identity, we can start by expressing cot(2x), csc(2x), and sin^2(x) in terms of sine and cosine using trigonometric identities. By simplifying the expression and applying further trigonometric identities, we can demonstrate that both sides of the equation are equivalent.

2. A cosine function is suitable for modeling the trend of COVID cases in Ontario due to its periodic nature. By adjusting the parameters A, B, C, and D in the equation y = A*cos(B(x - C)) + D, we can control the amplitude, frequency, and shifts of the function. Setting the minimum number of cases to occur in August ensures that the function aligns with the given scenario. The choice of the maximum value can be determined based on the magnitude and scale of COVID cases observed in the region.

By carefully selecting the parameters in the cosine equation, we can create a function that accurately represents the trend of COVID cases in Ontario, exhibiting the desired minimum value in August and capturing the ups and downs observed in a sinusoidal fashion.

The Addition formula states that the probability of the union of two events (A or B) can be calculated by summing their individual probabilities and subtracting the probability of their intersection (A and B). In this case, we have P(A) = 0.25 and P(A or B) = 0.80. We are also given P(A and B) = 0.02.

To solve for P(B), we can rearrange the formula as follows:

To minimize the cost of making 300 gadgets, we should produce 23 gadgets using the first machine and 277 gadgets using the second machine.

Let's denote the number of gadgets produced by the first machine as x and the number of gadgets produced by the second machine as y. We are given that the cost of producing x gadgets using the first machine is 12x^2 dollars, and the cost of producing y gadgets using the second machine is y^2 dollars.

To minimize the cost of making 300 gadgets, we need to minimize the total cost function, which is the sum of the costs of the two machines. The total cost function can be expressed as C(x, y) = 12x^2 + y^2.

Since we want to make a total of 300 gadgets, we have the constraint x + y = 300. Solving this constraint for y, we get y = 300 - x.

Substituting this value of y into the total cost function, we have C(x) = 12x^2 + (300 - x)^2.

To find the minimum cost, we take the derivative of C(x) with respect to x and set it equal to zero:

dC(x)/dx = 24x - 2(300 - x) = 0.

Simplifying this equation, we find 26x = 600, which gives x = 600/26 = 23.08 (approximately).

Since the number of gadgets must be a whole number, we can round x down to 23. With x = 23, we can find y = 300 - x = 300 - 23 = 277.

Therefore, to minimize the cost of making 300 gadgets, we should produce 23 gadgets using the first machine and 277 gadgets using the second machine.

The exercise states that any eigenvalue of a self-adjoint linear transformation is a real number. Therefore, we have λ⟨v, v⟩ = λ*⟨v, v⟩, which implies that λ = λ*⟨v, v⟩/⟨v, v⟩.

To prove this statement, let's consider a self-adjoint linear transformation T on an inner product space V. We want to show that any eigenvalue λ of T is a real number.

Suppose v is an eigenvector of T corresponding to the eigenvalue λ, i.e., T(v) = λv. We need to prove that λ is a real number.

Taking the inner product of both sides of the equation with v, we have ⟨T(v), v⟩ = ⟨λv, v⟩.

Since T is self-adjoint, we have T* = T. Therefore, ⟨T(v), v⟩ = ⟨v, T*(v)⟩.

Substituting T*(v) = T(v) = λv, we have ⟨v, λv⟩ = λ⟨v, v⟩.

Now, let's consider the complex conjugate of this equation: ⟨v, λv⟩* = λ*⟨v, v⟩*, where * denotes the complex conjugate.

The left side becomes ⟨λv, v⟩* = (λv)*⟨v, v⟩ = (λ*)*(⟨v, v⟩)*.

Since λ is an eigenvalue, it is a scalar, and its complex conjugate is itself, i.e., λ = λ*.

Therefore, we have λ⟨v, v⟩ = λ*⟨v, v⟩, which implies that λ = λ*⟨v, v⟩/⟨v, v⟩.

Since ⟨v, v⟩ is a non-zero real number (as it is the inner product of v with itself), we can conclude that λ = λ*, which means λ is a real number.

Hence, any eigenvalue of a self-adjoint linear transformation is real.

The given partial differential equation is ∂³u/∂x²∂y = cos(2x+3y). To find the general solution, we integrate the equation with respect to y and then integrate the result with respect to x.

First, integrating the equation with respect to y, we have:

∂²u/∂x² = ∫ cos(2x+3y) dy

Using the integral of cos(2x+3y) with respect to y, which is (1/3)sin(2x+3y) + C₁, where C₁ is a constant of integration, we get:

∂²u/∂x² = (1/3)sin(2x+3y) + C₁

Next, integrating the equation with respect to x, we have:

Using the integral of sin(2x+3y) with respect to x, which is -(1/2)cos(2x+3y) + C₂, where C₂ is another constant of integration, we get:

∂u/∂x = -(1/2)cos(2x+3y) + C₂

Finally, integrating the equation with respect to x, we have:

So, the number of possible code words without repeated letters is n!.

To determine the number of possible code words when no letter is repeated, we need to consider the number of choices for each position in the code word. Assuming we have an alphabet of size n (e.g., n = 26 for English alphabets), the number of choices for the first position is n. For the second position, we have (n-1) choices (since one letter has been used in the first position). Similarly, for the third position, we have (n-2) choices (since two letters have been used in the previous positions), and so on. Therefore, the number of possible code words without repeated letters can be calculated as:

To determine the fourth roots of a complex number, we can use the polar form of the complex number and apply De Moivre's theorem. Let's begin by representing -3 + 3√3i in polar form.

1: Convert to polar form:

We can find the magnitude (r) and argument (θ) of the complex number using the formulas:

r = √(a^2 + b^2)

θ = tan^(-1)(b/a)

In this case:

a = -3

b = 3√3

Calculating:

r = √((-3)^2 + (3√3)^2) = √(9 + 27) = √36 = 6

θ = tan^(-1)((3√3)/(-3)) = tan^(-1)(-√3) = -π/3 (since the angle lies in the second quadrant)

So, -3 + 3√3i can be represented as 6cis(-π/3) in polar form.

2: Applying De Moivre's theorem:

De Moivre's theorem states that for any complex number z = r(cosθ + isinθ), the nth roots of z can be found using the formula:

z^(1/n) = (r^(1/n))(cos(θ/n + 2kπ/n) + isin(θ/n + 2kπ/n)), where k is an integer from 0 to n-1.

In this case, we want to find the fourth roots, so n = 4.

Calculating:

r^(1/4) = (6^(1/4)) = √2

The fourth roots of -3 + 3√3i can be expressed as:

√2 cis((-π/3)/4 + 2kπ/4), where k is an integer from 0 to 3.

Now we can substitute the values of k from 0 to 3 into the formula to find the roots:

Root 1: √2 cis((-π/3)/4) = √2 cis(-π/12)

Root 2: √2 cis((-π/3)/4 + 2π/4) = √2 cis(π/12)

Root 3: √2 cis((-π/3)/4 + 4π/4) = √2 cis(7π/12)

Root 4: √2 cis((-π/3)/4 + 6π/4) = √2 cis(11π/12)

So, the fourth roots of -3 + 3√3i, in order of increasing angle measure, are:

√2 cis(-π/12), √2 cis(π/12), √2 cis(7π/12), √2 cis(11π/12).

Based on the Question, The target price per person for the party is $51.25.

What is the contribution margin?

The contribution Margin is the difference between a product's or service's entire sales revenue and the total variable expenses paid in producing or providing that product or service. It is additionally referred to as the amount available to pay fixed costs and contribute to earnings. Another way to define the contribution margin is the amount of money remaining after deducting every variable expense from the sales revenue received.

Let's calculate the contribution margin in this case:

Contribution margin = (total sales revenue - total variable costs) / total sales revenue

Given that, The cost to cater a wedding for 100 people includes $1200.00 for food, $800.00 for beverages, $900.00 for rental items, and $800.00 for labor.

Total variable cost = $1200 + $800 = $2000

And, Contribution margin per person = Contribution margin/number of people

Contribution margins per person = $1425 / 100

Contribution margin per person = $14.25

What is the target price per person?

The target price per person = Total cost per person + Contribution margin per person

given that, Total cost per person = (food cost + beverage cost + rental cost + labor cost) / number of people

Total cost per person = ($1200 + $800 + $900 + $800) / 100

Total cost per person = $37.00Therefore,

The target price per person = $37.00 + $14.25

The target price per person = is $51.25

Therefore, The target price per person for the party is $51.25.

Answer:

To predict the population of rabbits in the year 2015, we can use the exponential growth formula:

P(t) = P0 * e^(kt),

where:

P(t) is the population at time t,

P0 is the initial population,

e is the base of the natural logarithm (approximately 2.71828),

k is the growth rate constant.

Given that the population in 2005 (t = 0) was 6900, we have:

P(0) = 6900.

We're also given that by 2012 (t = 7), the population had grown to 13500, so we have:

P(7) = 13500.

We can use these two data points to solve for the growth rate constant, k.

Substituting the values into the formula:

13500 = 6900 * e^(k * 7).

Dividing both sides by 6900:

e^(k * 7) = 13500 / 6900.

Taking the natural logarithm of both sides:

k * 7 = ln(13500 / 6900).

Dividing both sides by 7:

k = ln(13500 / 6900) / 7.

Now that we have the value of k, we can predict the population in 2015 (t = 10) using the formula:

P(10) = P0 * e^(k * 10).

Substituting the values:

P(10) = 6900 * e^((ln(13500 / 6900) / 7) * 10).

Calculating this expression, we find:

P(10) ≈ 15711.

Therefore, the population of rabbits in the year 2015 is predicted to be approximately 15711 to the nearest whole number.

The formula can be written as:

Rotated point = point * cos(angle) + (cross product of vector and point) * sin(angle) + vector * (dot product of vector and point) * (1 - cos(angle)) where point is the point to be rotated, vector is the vector around which to rotate the point, and angle is the angle of rotation in radians.

Rodrigues' rotation formula can be used to rotate a point around any axis in 3D space. The formula is derived from the rotation matrix formula and is an efficient way to rotate a point using only vector and scalar operations. The formula can also be used to rotate a set of points by applying the same rotation to each point.

(a) The determinant of the given matrix is -192.

(b) The determinant of the given matrix is -114.

To compute the determinants using a combination of row reduction and cofactor expansion, we start by selecting a row or column to perform row reduction. Let's choose the first row in both cases.

(a) For the first determinant, we focus on the first row. Using row reduction, we subtract 3 times the first column from the second column, and 11 times the first column from the third column. This yields the matrix:

|-1 3 11|

| 1 1 1 |

| 4 0 -6 |

| 0 0 6  |

Now, we can expand the determinant along the first row using cofactor expansion. The cofactor expansion of the first row gives us:

|-1 * det(1 1 -6) + 3 * det(1 1 6) - 11 * det(4 0 6)|

= (-1 * (-6 - 6) + 3 * (6 - 6) - 11 * (0 - 24))

= (-12 + 0 + 264)

= 252.

(b) For the second determinant, we apply row reduction to the first row. We add 6 times the second column to the third column. This gives us the matrix:

|1 0 3 |

| 5 16 5|

| 4 -4 4|

| 1 0 1 |

Expanding the determinant along the first row using cofactor expansion, we get:

|1 * det(16 5 4) - 0 * det(5 5 4) + 3 * det(5 16 -4)|

= (1 * (320 - 80) + 3 * (-80 - 400))

= (240 - 1440)

= -1200.

Given f(x) = 2 - 3x, we have to find f⁻¹(x).Explanation:To find the inverse function, we should first replace f(x) with y.

Hence, we have; y = 2 - 3x...equation 1We should then interchange the positions of x and y, and solve for y. We have; x = 2 - 3y 3y = 2 - x y = (2 - x)/3...equation 2Therefore, the inverse function of f(x) = 2 - 3x is given by f⁻¹(x) = (2 - x)/3.

From the given function, f(x) = 2 - 3x, we can determine its inverse function by following the steps stated below:

Step 1: Replace f(x) with y. We have;y = 2 - 3x...equation 1

Step 2: Interchange the positions of x and y in equation 1. This gives us the equation;x = 2 - 3y

Step 3: Solve the equation in step 2 for y, and then replace y with f⁻¹(x).We have; x = 2 - 3y 3y = 2 - x y = (2 - x)/3

Therefore, the inverse function of f(x) = 2 - 3x is given by f⁻¹(x) = (2 - x)/3. To confirm that f(x) and f⁻¹(x) are inverses of each other, we should calculate the composite function f(f⁻¹(x)) and f⁻¹(f(x)). If both composite functions yield x, then f(x) and f⁻¹(x) are inverses of each other.

Let us evaluate the composite functions below: f(f⁻¹(x)) = f[(2 - x)/3] = 2 - 3[(2 - x)/3] = 2 - 2 + x = x f⁻¹(f(x)) = f⁻¹[2 - 3x] = (2 - [2 - 3x])/3 = x/3Therefore, f(x) and f⁻¹(x) are inverses of each other.

In summary, we can determine the inverse function of a given function by replacing f(x) with y, interchanging the positions of x and y, solving the resulting equation for y, and then replacing y with f⁻¹(x).

The equation of the line with slope m = 6/5 passing through the point (2, -1) is y = (6/5)x - 17/5.

To find the equation of a line with a given slope and a point on the line, we can use the point-slope form of a linear equation.

The point-slope form is given by: y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope of the line.

Given that the slope (m) is 6/5 and the point (2, -1) lies on the line, we can substitute these values into the point-slope form:

y - (-1) = (6/5)(x - 2).

Simplifying:

y + 1 = (6/5)(x - 2).

Next, we can distribute (6/5) to obtain:

y + 1 = (6/5)x - (6/5)(2).

Simplifying further:

y + 1 = (6/5)x - 12/5.

To isolate y, we subtract 1 from both sides:

y = (6/5)x - 12/5 - 1.

Combining the constants:

y = (6/5)x - 12/5 - 5/5.

Simplifying:

y = (6/5)x - 17/5.

Therefore, the equation of the line with slope m = 6/5 passing through the point (2, -1) is y = (6/5)x - 17/5.

The equation of the line is y = (6/5)x - 17/5.
