If you are solving y 2+2y=48 by completing the square, the next line would be y 2 + 2y - 48 = 0
y 2 + 2y + 4 = 52
y 2 + 2y + 1 = 49

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. : )
