Answer:
Part A) 25
Part B) 225
Step-by-step explanation:
Part A
The slope of the graph gives us the mile per gallon of the car.
Recall that the slope of the graph is rise over run.

Therefore car gets 25 miles per gallon
Part B) Since we know the slope of the direct variation line, we substitute into y=kx to get:

To find the number of miles the car travels using 9 gallons, we substitute x=9 to get:

This gives us 225 miles

Answer:
(x, y) = (3, -1)
Step-by-step explanation:
The solution to the system of equations is the point where the lines intersect.
(x, y) = (3, -1)
The answer is z = 4 because of you put 4 into the equation it equals to 100
