Question

1. Which equation describes the line that passes through (–3, 1) and is parallel to the line described by y = 4x + 1?Which equation describes the line that passes through (–3, 1) and is parallel to the line described by y = 4x + 1?

A y = 4x + 13

B y = 4x – 1

C y= -1/4x + 7/4

D y= -1/4x + 1/4

Answer 1

m = 4 at point (-3,1)

y = 4x + c
1 = 4(-3) + c
1 = - 12 + c
c = 13
y = 4x + 13
