Rate of Change represents the number of apartments cleaned each hour & this is linear.
We immediately note that 3 and 9 are multiples. Therefore, they are factorable. 9 goes into 3 three times, and 3 goes into three 1 time. Therefore, we can take out three from the whole expression to get 3(c - 3).

(4-12)/4
-8/4
-2
So the average rate of change is -2.
