7%2Ax%2B8%2Ay=56 Start with the given equation

To find the y-intercept, let x=0 and solve for y:
7%2A%280%29%2B8%2Ay=56 Plug in x=0

8%2Ay=56 Simplify

x=56%2F8 Divide both sides by 8



y=7 Reduce



So the y-intercept is (0,7) (note: the y-intercept will always have a x-coordinate equal to zero)
