20x%2B8y=32 Start with the given equation.


8y=32-20x Subtract 20x from both sides.


8y=-20x%2B32 Rearrange the terms.


y=%28-20x%2B32%29%2F%288%29 Divide both sides by 8 to isolate y.


y=%28%28-20%29%2F%288%29%29x%2B%2832%29%2F%288%29 Break up the fraction.


y=-%285%2F2%29x%2B4 Reduce.


So the equation y=-%285%2F2%29x%2B4 is now in slope intercept form y=mx%2Bb where the slope is m=-5%2F2 and the y-intercept is b=4

note: the y-intercept is the point
