How do you write the equation in slope intercept form given (2,2) and (0,-2)?

Answers

Answer:

y = 2x - 2

Step-by-step explanation:

The slope-intercept form of the equation of a line is

y = mx + b

where m is the slope, and b is the y-intercept.

y = mx + b

First we find the slope, m.

slope = (difference in y)/(difference in x)

It does not make a difference which point is first and which point is second in finding the differences, but you must do the x- and y-differences in the same order.

slope = (-2 - 2)/(0 - 2) = -4/(-2) = 2

The slope is 2, so m = 2, and now we have:

y = 2x + b

We need to find the value of b, the y-intercept.

We use one of the given points. Let's use (2, 2). We plug in 2 for x and 2 for y and solve for b.

2 = 2(2) + b

2 = 4 + b

-2 = b

b = -2

Now that we know the y-intercept is -2, we substitute b with -2.

y = 2x + b

y = 2x - 2

Answer: y = 2x - 2

Find value of x and y​

Answers

Answer:

x = 60

y = 80

Step-by-step explanation:

x° + 120° = 180° (interior angles on the same side of transversal)

x° = 180° - 120°

x° = 60°

x = 60

x° + y° = 140° (alternate angles)

60° + y° = 140°

y° = 140° - 60°

y° = 80°

y = 80

The measure of angle ∠x is 60° and ∠y is 80°.

What are Alternate Interior Angles?

Alternate Interior Angles is defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. These angles are always equal.

Since angle ∠x and ∠120° are interior angles on the same side of transversal.

So, x° + 120° = 180°

x° = 180° - 120°

x° = 60°

x = 60

Since angle ∠x° and angle ∠y° are alternate angles

So, x° + y° = 140°

Substitute the value of x = 60 in above equation,

60° + y° = 140°

y° = 140° - 60°

y° = 80°

Hence, the measure of angle ∠x is 60° and ∠y is 80°.

Answers

Answer:

see below

Step-by-step explanation:

6y = 12x + 26

15y = 45x + 60

First let's simplify these equations.

6y = 12x + 26

Divide each term by 6.

y = 2x + 26/6

Simplify the fraction.

26/6

= 13/3

Your simplified equation is:

y = 2x + 13/3

Let's simplify the other equation.

15y = 45x + 60

Divide each term by 15.

y = 3x + 4

These are your simplified equations.

y = 2x + 13/3

y = 3x + 4

We can see that the slope of the first equation is not equal to the slope of the second equation.

equation 1: slope is 2 shown from 2xequation 2: slope is 3 shown from 3x

The y-intercept of the first equation is not equal to the y-intercept of the second equation.

equation 1: y-intercept is 13/3 shown by + 13/3equation 2: y -intercept is 4 shown by + 4

Now we want to solve the equations.

Both equations are equal to y, so you can set them equal to each other.

2x + 13/3 = 3x + 4

Combine like terms.

1/3 = x

Plug x = 1/3 into both of the equations separately..

y = 2(1/3) + 13/3

y = 2/3 + 13/3

y = 15/3

y = 5

y = 3(1/3) + 4

y = 3/3 + 4

y = 1 + 4

y = 5

Your solution is (1/3, 5)

The system of equations has one solution.

3 times a day Dylan mixes 2 oz of protein powder into a shake how many days can he make all 3 shakes from his 5 oz container of protein powder you #16 oz in a #

Answers

Answer:

13 days

Step-by-step explanation:

Protein powder in container = 16 oz

Number of containers = 5

Total ounces of protein powder = (16 * 5) = 80 oz

Oz of protein used per shake = 2 oz

Number of times shake is made per day = 3

Total oz used per day = 2 oz * 3 = 6 oz

Number of days hencan make all three shakes from container :

Total ounces / ounces per day
