Answer
(a) See Graph Below
(b) The slope represents the number of units of space omitted for every dollar increase. The y-int represents the maximum amount he can rent which is 200 spaces (the cost being 0). The x-int represents the amount he charges to rent 0 number of spaces.
Work Step by Step
(a) Rough Graph of the linear function as shown.
(b) The slope = x-coefficient = -4. If you let x=1, the number of units is 196. If you let x=2, the number of units is 192 - you subtract it by 4. Hence the slope represents the number of units of space that is unable to be rented for every dollar increased. The y-int occurs when x=0 - when the No. of units is 200. And this is the absolute maximum he can rent out if he made the cost 0. The x-intercept represents the amount he charges so that he is unable to rent any houses. This cost is $50.
