All right, so for this question, we are asked to create a function based off a constant rate of change.
00:09
So it's going to be a linear function.
00:13
So let's go ahead and draw a quick table with x and y.
00:18
So in 2011, which is going to be our year zero, the car was worth $10 ,500.
00:25
In 2013, which is two years from 2011, the car was worth $7 ,000.
00:32
300.
00:34
So we're going to go ahead and find the slope.
00:37
We're going to use change in y over change in x.
00:42
Or essentially we're going to go ahead and do 7 ,300 minus 10 ,500 over 2...
