2x-5y=20 Start with the given equation.


-5y=20-2x Subtract 2x from both sides.


-5y=-2x%2B20 Rearrange the terms.


y=%28-2x%2B20%29%2F%28-5%29 Divide both sides by -5 to isolate y.


y=%28%28-2%29%2F%28-5%29%29x%2B%2820%29%2F%28-5%29 Break up the fraction.


y=%282%2F5%29x-4 Reduce.


So the equation y=%282%2F5%29x-4 is now in slope intercept form y=mx%2Bb where the slope is m=2%2F5 and the y-intercept is b=-4

note: the y-intercept is the point
