x%2B7y=14 Start with the given equation.


7y=14-x Subtract x from both sides.


7y=-x%2B14 Rearrange the terms.


y=%28-x%2B14%29%2F%287%29 Divide both sides by 7 to isolate y.


y=%28%28-1%29%2F%287%29%29x%2B%2814%29%2F%287%29 Break up the fraction.


y=-%281%2F7%29x%2B2 Reduce.


So the equation y=-%281%2F7%29x%2B2 is now in slope intercept form y=mx%2Bb where the slope is m=-1%2F7 and the y-intercept is b=2 note: the y-intercept is the point
