Answer:
a.

b.


c.


Step-by-step explanation:
a.
using the point-slope form we have that:
y= mx + b
m being the slope which has the next equation:
y is the rent price
x is the units of the apartment complex rented


Now we find the Y intercept (b):
580=-15(50)+b
580=-750+b
b=580+750 = 1330
We have the equation:
y=-15x + 1330
Now we have tu put in terms of the rent p (y)
y=-15x + 1330
15x = 1330 - y

b.
The first graph attached corresponds to the equation showed in point a.
The second graph attached corresponds to the equation if the rent is $655
Using the trace feature it is estimated that for a rent price of $655 the units occupied are 45.


c. The third graph attached corresponds to the equation if the rent is $610
Using the trace feature it is estimated that for a rent price of $610 the units occupied are 48.
