The Rivera family and the Morgan family each used their sprinklers last summer. The water output rate for the Rivera family’s sprinkler was 35L per hour. The water output rate for the Morgan family’s sprinkler was 15L per hour. The families used their sprinkler for a combined Total of 45 hours resulting in a Total water output of 1175L how long was each sprinkler used?

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. : )

most likely linear (proportionate)
