Answer:
8.57% rebate
Step-by-step explanation:
100 / 35 = 2.85714285714
2.85714285714 * 3 = 8.57142857143
8.57142857143 ---> 8.57%

Remark
I hope you don't mind if I laughed a little at the graph. The y intercept of the line is at 10 dollars, but the rental car has not moved an inch. I guess they're charging you to look at your driver's license. It's late, and maybe I am a little giddy.
Begin by using a ruler (or some other straight edge) to join all the dots.
a) I'll spend a little time here. It is very important that you know how to read a chart and this question is your first step. The question is how many dollars does it take to go 40 miles? There is a system. Start with the 40 miles on the horizontal axis (x axis if you know that that is).
Use a ruler to go straight up until you hit the line.
- When you hit the line, mark the place.
- Now move straight across until you hit the y axis where you find out the money.
- You should get 30 dollars.
b) This question is a guess.
- You can find the 70 dollars easily enough. Go straight up again until you hit the line.
- Mark the point on the line.
- Go straight across again.
- Not so easy. It isn't marked. You have to make a guess. My guess is 45. What do you think?
c) This question is the exact reverse of the other two.
- This time you start with the amount of money
- So you start at 60 dollars and go straight across until you hit the line.
- Mark the point.
- Now take your ruler and go straight down.
- You should hit 100 miles.

Answer:
(x-5)²+(y-2)²=52
Step-by-step explanation:
first find the midpoint (center of the circle)
(9+1)/2, (-4+8)/2
(5, 2) = center
then distance formula to find diameter
√(9-1)²+(-4-8)²=√64+144 = √208 = 2√52
The radius is half the diameter = √52
Formula for circle is (x-h)²+(y-k)²=r², where (h, k) is the center
Now you can plug everything in.
(x-5)²+(y-2)²=52
