6x-3y=72 Start with the given equation.


-3y=72-6x Subtract 6x from both sides.


-3y=-6x%2B72 Rearrange the terms.


y=%28-6x%2B72%29%2F%28-3%29 Divide both sides by -3 to isolate y.


y=%28%28-6%29%2F%28-3%29%29x%2B%2872%29%2F%28-3%29 Break up the fraction.


y=2x-24 Reduce.


So the equation y=2x-24 is now in slope intercept form y=mx%2Bb where the slope is m=2 and the y-intercept is b=-24

note: the y-intercept is the point
