The y-coordinate of the y-intercept is the value of b in y=mx%2Bb, the x-coordinate of a y-intercept is always 0. That is because the x-coordinate of ANY point on the y-axis is 0.

Your equation is in standard form, ax%2Bby=c, so all you need to do is solve the equation for y, that is, manipulate the equation by any valid means to isolate the y on the left side of the equation. Whatever is then on the right side after you have collected like terms if necessary is going to be in the form of mx%2Bb. Whatever value is in the place of the b is the y-coordinate and the ordered pair describing your intercept point is (0,b).
