3x-4y=80 Start with the given equation


-4y=80-3x Subtract 3+x from both sides


-4y=-3x%2B80 Rearrange the equation


y=%28-3x%2B80%29%2F%28-4%29 Divide both sides by -4


y=%28-3%2F-4%29x%2B%2880%29%2F%28-4%29 Break up the fraction


y=%283%2F4%29x-20 Reduce



So the equation is now in slope-intercept form (y=mx%2Bb) where the slope is m=3%2F4 and the y-intercept is b=-20
