What is the point-slope form of a line?If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).
Given the graph of the equation.
Note that the graph passes through points (0,0) and (2,90).
The slope of the line is:
m = (90 - 0)/(2 - 0)
m = 45
The equation of the line with a slope of m = 45 and passes through (0,0) is:
y -0 = 45(x - 0)
y = 45x
Hence, the equation y = 45 models the saving.

Piper used 1/5 meter of ribbon to create a border around a triangle if each side of the triangle is the same length how much ribbon did Piper use for each side?
Answers
Answer:
[tex]\frac{1}{15}[/tex]
Step-by-step explanation:
as said in the question that the triangle has three equal sides. i.e. this is an equilateral triangle. So,
let us consider one side of the triangle to be x . and 3x( x+x+x) should be equal to 1/5
[tex]x+x+x = \frac{1}{5}\\3x=\frac{1}{5}\\x = \frac{1}{5} / 3\\x = \frac{1}{5} * \frac{1}{3}\\x = \frac{1}{15}[/tex]

Find the x and y intercepts of the line
Answers
Answer:
The x-intercept of the line is [tex]-\frac{3}{7}[/tex]
The y-intercept of the line is 3
Step-by-step explanation:
If the equation of a line is y = m x + b, then
The x- intercept is the value x at y = 0, (that means, the line intersect the x-axis at point (x, 0)The y-intercept is the value of y at x = 0, (that means, the line intersect the y-axis at point (0, y)Let us use these facts to solve the question
∵ y = 7x + 3
→ Substitute y by 0 to find the x-intercept
∵ y = 0
∴ 0 = 7x + 3
→ Subtract 3 from both sides
∵ 0 - 3 = 7x + 3 - 3
∴ -3 = 7x
→ Divide both sides by 7 to find x
∵ [tex]-\frac{3}{7}[/tex] = [tex]\frac{7x}{7}[/tex]
∴ [tex]-\frac{3}{7}[/tex] = x
∴ The x-intercept of the line is [tex]-\frac{3}{7}[/tex]
∵ y = 7x + 3
→ Substitute x by 0 to find the y-intercept
∵ x = 0
∴ y = 7(0) + 3
∴ y = 0 + 3
∴ y = 3
∴ The y-intercept of the line is 3
Slope of (3, -9) (3, 18)

Answer:
Undefined.
Step-by-step explanation:
To calculate the slope between two points on a graph, we use [tex]\frac{y2-y1}{x2-x1}[/tex].
Once we substitute in the provided points, this becomes [tex]\frac{18-(-9)}{3-3}[/tex].
Simplify to [tex]\frac{27}{0}[/tex].
This does not give us a number and instead results in an undefined slope, aka a vertical line.

Which two answer choices below would give you a value of 3 times larger than (820 + 220)?
A) 3(820 + 220)
B) 3(820) + 2(220)
C) 2460 + 660
D) 820 x 220 x 3
Answers
The expression that gives you a value of 3 times larger than (820 + 220) are:
3(820 + 220)
2460 + 660
Options A and C are the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(820 + 220)
= 1040
Now,
3 x 1040
= 3120
Now,
A)
3(820 + 220)
= 3 x 1040
= 3120
B)
3(820) + 2(220)
= 2460 + 440
= 2900
C)
2460 + 660
= 3120
D)
820 x 220 x 3
= 541200
Thus,
3(820 + 220) and 2460 + 660 give the value of 3 times larger than
(820 + 220).

Step-by-step explanation:

(x,y) -> (-x,-y)
So the x and y coordinates change from negative to positive or from positive to negative
9514 1404 393
Answer:
180°
Step-by-step explanation:
When you look at the coordinates, you see that each one has been negated. That is, the image point is in the quadrant opposite the one the preimage point is in.
Every point and its image on a rotated figure makes an angle with the center of rotation that is equal to the angle of rotation. When the preimage and image points are in opposite (not adjacent) quadrants, that angle is 180°.
______
Additional comment
It can be helpful to learn to recognize certain transformations. A rotation of 90° will swap the coordinates and negate one of them. A rotation of 180° negates both coordinates without swapping them.
