Answer:

Step-by-step explanation:
Honestly not sure what all the numbers you put down were (numbers for the graph?), but here is how to find the slope :)
First, find two "exact" points!
I am going to use (0, 1) and (2, 2)
We then go to our first point, (0, 1), and count how many points up it is until we are on the same x-axis of our y. This is 1. We then do the same thing for the y-axis. This is 2. It is rise over run, so the answer is 
(I hope this helps, have a nice day!)
1) Subtract 1,000 from 16,000.
Now you have 15,000.
2) Divide 15,000 by 3.
The original price of the car was $5,000.
