Question

Which is the equation of a line parallel to the line with equation y = 3x - 4?
Answer x - 3y = 1
3x + y = 7
x + 3y = 4
3x - y = -2

Answer 1

parallel means it has the same slope

rearrange them make y subject
the last one is the answer

Answer 2

okay so our of those answers...
we have y = 1/3x -1/3 - wrong slope

Answer 3

3x + y = 7 --> y = -3x + 7 ... wrong slope

Answer 4

x + 3y = 4 --> y = -1/3x + 4/3 .. nope

Answer 5

3x - y = -2 --> y = 3x + 2... same slope

Answer 6

cause the coefficient with the x ... are the same.. the yintercept doesnt matter in parallels and perpendicular
