In the equation Ax + By = C, what is the y-intercept?

Explanation:
The y-intercept is the y-coordinate when x equals 0. From Ax + By = C, solve for y: By = -Ax + C, so y = (-A/B)x + C/B. When x = 0, y = C/B. So the y-intercept is C/B. (If B = 0, the line is vertical and has no y-intercept.) The other expressions don’t come from setting x to 0 and solving for y.
