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. : )
