Solution :

Given The rate of change is represented in this formula;
y= 3.63+1.22x
this is in 2 year
then in 1 year = (3.63+1.22x)/2
the annual rate of change=1.815+0.61x

What exactly do you mean by this? That y is changing in this way? Or that y gives the rate of change of some other quantity?

And what do you mean by this? The rate of change "over a period of two years" does not tell us anything about what the rate of change of any shorter (or longer) period might be.

What is the annual rate of change?

Thanks
