Did I do this right? Or do I need to start over.

Find the slope of the line described.
A line perpendicular to -4x+4y=-2

-4x+4y=-2
4y=4x-2
4y/4=4x-2/4
y=1x-1/2

Yes, but you are not finished

4 y = 4 x -2
slope of original line is 4/4 = 1
NOW we need perpendicular
slope of perpendicular = -1/slope of original
so slope we want = -1/1 = -1
