which of the following equations has a graph that is parallel to the graph of 4x-2y=7?

1)4x+2y=2
2)-2y=4x+2
3)7-4x=2y
4)2y=4x+7
5)-4x-2y=-7

After re-arranging
1) 2) 3) and 5) all would start with 4x + 2y ...
so clearly they cannot be parallel to 4x - 2y ....

4) ----> 0 = 4x - 2y + 7
ahhhh, that's the one !
Enter the slope of a line perpendicular to the line whose equation is 3y-5x=15
