    40 is the y-int, so your first point should be (0,40)

    To find the other point, set y = 0, and solve for x

    If it is true after substituting (0,0), then the shading goes below the graph of the line. If it is not true after testing, then the shading goes above the line.

    And after testing the point (0,0) it is true, so therefore the shading goes below the line.
