The manager of a weekend flea market knows from past experience that if he charges x dollars for a rental space at the flea market, then the number of spaces he can rent is given by the equation y = 200 - 4x.
(a) Sketch a graph of this linear function. (Remember that the rental charge per space and the number of spaces rented can't be negative quantities.)
(b) What do the slope, the y-intercept, and the x-intercept of the graph represent?
