So this problem is asking us to find the depreciation equation for this toyota tundra.
00:07
Now, as you can see in this chart i've written, once the toyota tundra was bought, it was worth $24 ,300.
00:15
So when zero years had passed, the value was $24 ,300.
00:19
Then, after seven years, the salvage value had become $1 ,900.
00:25
So after seven years, the value is $1 ,900.
00:27
Now, we can put this into coordinates by making the x coordinate the years and the y coordinate the values.
00:34
So we'll end up with two coordinates that are 0 ,24 ,300, and the second one being 7 ,1 ,900.
00:47
Now, in order to find the depreciation equation, we have to find the slope first.
00:53
The slope is always the change in y over the change in x.
00:58
Now, in order to find the change in y, we'll have to do 1 ,900 minus 24 ,300 over the change in x, which will be 7 minus 0...
