    A $675 stereo receiver loses value at a rate of about $18 per month The equation y = 675 - 18x represents the value of the receiver after x months. Identify and interpret the x- and y-intercepts. Explain how you can use the intercepts to help you graph the equation

    y = 675 - 18x

    The y-intercept is found when x is 0:
    y = 675 - 18(0)
    y = 675 - 0
    y = 675

    The x-intercept is found when y is 0:
    0 = 675 - 18x

    Typing this equation into our search engine, we get:
    x = 37.5
