Using it's concept, the rate of change between point C and point D is of 2.
<h3>What is the average rate of change of a function?</h3>The average rate of change of a function is given by the <u>change in the output divided by the change in the input</u>. Hence, over an interval [a,b], the rate is given as follows:
Considering the points of the given linear function, we have that:
- Point C: f(1) = 2.
- Point D: f(2) = 4.
Hence the rate of change between point C and point D is given by:
r = (4 - 2)/(2 - 1) = 2.

We know that:
is an equation of a circle.
When we substitute x and y (from the pairs we have), we'll get a system of equations:
and all we have to do is solve it for a, b and r.
There will be:
From equations (II) and (III) we have:
and from (I) and (II):
Now we can easly calculate a and b:
Finally we calculate
