    The x-intercept is found by substituting y = 0. Solve.
    The y-intercept is found by substituting x = 0. Solve.

    This is a very inportant concept that you should pound into your brain.

    x-intercepts look like this (a,0)
    y-intercepts look like this (0,b)

    More still. The form of the equation that you ahve presented is the "Slope-Intercept" form. It means the y-interecept is staring at you.

    y=4x+3 ==> y-intercept is (0,3)
    The x-intercept is a hair trickier.
