(a) Draw a graph of this linear function. (Note that renting a unit area and the size of rentable space cannot be negative.)

(b) In this case, find the slope of the graph, the intersection of the x-axis and the y-axis.

Answer 1

(b) The slope of the graph is -4. The intersection of the x-axis is (50,0).

The intersection of the y-axis is (0,200).
