Question

Which is the equation of a line parallel to the line with equation y = 3x - 4

A. x + 3y = 4
B. x - 3y = 1
C. 3x - y = -2
D. 3x + y = 7

Answer 1

C. 3x - y = -2

Explanation:

We know that lines with the same slope are usually parallel

3x - y = -2

-y = -3x - 2

y = 3x + 2

They have the same slope so we can assume that they're parallel
