Nancy walked 516 yards in 6 minutes and then another 368 yards in 4 minutes. what was nancy's average speed? * a. 89 yd/min b. 89.4 yd/min c. 88.4 yd/min d. 178 yd/min

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!

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. : )
