To find the y-intercept of the equation, we need to have x = 0 and then find the y-intercept. Then, we have:
The original equation:

If we have x = 0, then y is:

Therefore, the y-intercept as an ordered pair is (0, -2).
The y-intercept is the point where the line crosses the y-axis. In the y-axis, the value for the coordinate x is x = 0 to get the value for y (that is, the y-intercept).
