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:
Hence the rate of change between point C and point D is given by:
r = (4 - 2)/(2 - 1) = 2.

The value decimal point is changing going to the right as you divide a number by 10.
For example
=> 2000.3 / 10
notice the decimal point
=> 200.013, the value of decimal numbers increases as the value of whole number decreases.Let’s divide again
=> 200.013 / 10
=> 20.0013 , now we already have 4 digits in our decimals.
So, simply as we divide the given number by 10, the decimal point moves to the left making the value of whole number decreases and making the number of digits of decimal increase.
The answer is B.
Whatever the x value is you have to add 9 to it.
