A construction team is building several buildings. They want the average time spent on each building to be 15 hours or less. So far, they have spent thr following times for the first 4 buildings:17 hours, 10 hours,19 hours, 13 hours. How many hours should thry spend building ghr fifth building in order to match there goal of an average of 15 hours or less?

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. : )
