Question 7 of 10 What is the result of substituting for y in the bottom equation?
y = x-7
y = x^2 + 2x - 4
A. x- 7 = x2 + 2x - 4
B. y = (x - 7)2 + 2(x – 7) – 4
O c. x- 7 = x2
O D. y = x2 + 2x - 4 - (x - 7)

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
