3x%2B4y=8 Start with the given equation.


4y=8-3x Subtract 3x from both sides.


4y=-3x%2B8 Rearrange the terms.


y=%28-3x%2B8%29%2F%284%29 Divide both sides by 4 to isolate y.


y=%28%28-3%29%2F%284%29%29x%2B%288%29%2F%284%29 Break up the fraction.


y=-%283%2F4%29x%2B2 Reduce.


So the equation y=-%283%2F4%29x%2B2 is now in slope intercept form y=mx%2Bb where the slope is m=-3%2F4 and the y-intercept is b=2 note: the y-intercept is the point
