13. Two ramps are placed back to back as shown. What is the length of the ramp labeled x? 3.6 ft.
6.9 ft .
7.5 ft.
8.0 ft.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

to be honest i don't know but i need points so
