    The x-intercept is where the graph crosses the x-axis. y = 0
    -4x+2 * 0=32
    divide each side by -4
    x = -8

    The y-intercept is where the graph crosses the y-axis. x = 0
    -4 * 0+2y=32
    divide each side by 2
    y= 16

    Finding the intercepts is easy as pie. To find the x-intercept (x,0), you simply substitute 0 for y and solve for x. To find the y-intercept (0,y), you simply substitute 0 for x and solve for y.

    x-intercept

    -4x+2(0) = 32 --> x = -8 --> x-int = (-8,0)

    y-intercept

    -4(0)+2y = 32 --> y = 16 --> y-int = (0,16)
