Tyler needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 5 hours and charged him $112 for parts. The total was $237. What was the cost of labor, per hour?

3; 9 is 8 to -4

step-by-step explanation:

1; 35 is the ratio

step-by-step explanation:

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. : )
