2x-5y=45 Start with the given equation.


-5y=45-2x Subtract 2x from both sides.


-5y=-2x%2B45 Rearrange the terms.


y=%28-2x%2B45%29%2F%28-5%29 Divide both sides by -5 to isolate y.


y=%28%28-2%29%2F%28-5%29%29x%2B%2845%29%2F%28-5%29 Break up the fraction.


y=%282%2F5%29x-9 Reduce.


So the equation y=%282%2F5%29x-9 is now in slope intercept form y=mx%2Bb where the slope is m=2%2F5 and the y-intercept is b=-9 note: the y-intercept is the point
