anonymous · Answer

Average rate of change is basically like the calculating slope. you always start with the second point and then subtract the first point.

anonymous · Answer

In this case the second point will be (12,8.75) and first point will be (4,2.75)

anonymous · Answer

$$AOR=\frac{ 8.75-2.75 }{ 12-4}$$
AOR=$0.75/week
