Answer by adamchapman(301)   (Show Source): You can put this solution on YOUR website!Two lines are parralel if they have the same gradient. When the equation of a line is written in the form "y=mx+c", "m" represents the gradient. The second equation is already in the form we want, and we can see that the gradient is 1/4. Rearrange the first equation: -8x + 2y = 8 2y = 8x + 8 y = 4x + 4. The gradient of this line is 4. 1/4 is not the same as 4, so the two lines are not parallel. I hope this helps. P.S.
