I'm assuming you want to solve for 'y' right?


2x%2B2y=6 Start with the given equation.


2y=6-2x Subtract 2x from both sides.


2y=-2x%2B6 Rearrange the terms.


y=%28-2x%2B6%29%2F%282%29 Divide both sides by 2 to isolate y.


y=%28%28-2%29%2F%282%29%29x%2B%286%29%2F%282%29 Break up the fraction.


y=-x%2B3 Reduce.


So the equation y=-x%2B3 is now in slope intercept form y=mx%2Bb where the slope is m=-1 and the y-intercept is b=3 note: the y-intercept is the point
