**Steve**, Friday, August 23, 2013 at 4:22amI don't know how you can have trouble at the site. If you just enter

7/(4x-4)

and

-1/(4x+4)

into the first two function boxes, and click "Draw", you will see the graphs and where they intersect. That appears to be (-3/4,-1).

Algebraically, set them equal:

7/(4x-4) = -1/(4x+4)

7(4x+4) = -1(4x-4)

28x+28 = -4x+4

32x = -24

x = -3/4

so, y = 7/(-7) = -1
