4x-2y=8 Start with the given equation.


-2y=8-4x Subtract 4x from both sides.


-2y=-4x%2B8 Rearrange the terms.


y=%28-4x%2B8%29%2F%28-2%29 Divide both sides by -2 to isolate y.


y=%28%28-4%29%2F%28-2%29%29x%2B%288%29%2F%28-2%29 Break up the fraction.


y=2x-4 Reduce.


So the equation y=2x-4 is now in slope intercept form y=mx%2Bb where the slope is m=2 and the y-intercept is b=-4 note: the y-intercept is the point
