12.passes through (-3,-1), parallel to a line whose slope is -1
A machine that originally cost $15,600 has a value of $7500 at the end of 3 years. The same machine has a value of $2800 at the end of 8 years.
13. Find the average rate of change in value (depreciation) of the machine between its purchase and the end of 3 years.
14. Find the average rate of change in value of the machine between the end of 3 years and the end of 8 years.
