Question 109404: I dont understand this. I thought I did and didnt get parallel lones. Determine which two equations represent parallel lines.
(a) y =5/7 x + 3(b) y =-7/5x – 7(c) y = 2x + 12(d) y = 2x – 3

You can put this solution on YOUR website!
c and d both have slope = 2, so they are parallel lines.
