a $675 stereo receiver loses value at a rate of $18 a 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 interprets to help you graph the equation

x-intercept is where y=0, 675-18x=0, x = 675/18 = 37.5 (months). It is the time when the receiver will lose all its value.

y-intercept is where x=0, y = 675 (dollars). It is the start price.

This equation is linear and its graph is a straight line. To draw this line any two distinct points of the line are suitable, intercepts also. Their coordinates are (37.5, 0) (x-intercept) and (0, 675) (y-intrecept).
