You first have to put 8x-4y=8 into y=mx+b 
So -4y=8x+8
You have to get y alone 
so you divide each side by -4 y=-2x-2
the slope is -2

8x - 4y = 8. Change to form y = mx + c.    Where m = slope

-4y = -8x + 8.      Divide both sides by 4.

-4y/-4 =  (-8x + 8)/-4

  y = 2x - 2.    Compare to y = mx + c.

Slope,  m = 2.
