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

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

lalaly · Answer

parallel means it has the same slope

rearrange them make y subject
the last one is the answer

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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