Average rate of change would be 223.028
2)
Here rate of change means
change in y due to x.
For, 2000-2001, rate of change would be 0.
3) Scatter plot would be as followed:

y=0,00502x-1.33
In this context, y is a dependent variable slope is
0.00502 and x is independent variable, here the
slope shows that the 0.00502 amount change in x would be the rate
change in the y.
In simple words slope states the rate of change in y due to
changes in x.
