The y-intercept is where a graph crosses (or intersects) the y-axis. Think about the points on the y-axis. Think about the coordinates of points on the y-axis. After some thought I hope it is obvious the all the points on the y-axis have an x-coordinate of 0. So to find the y-intercept of a function, use a value of 0 for x. IOW, f(0) is the y-intercept.
So the y-intercept is (0, -5).
