In order to answer this, you need to find the equation of the line. The equation of a line is y= mx + b; mx being the slope and b being the y- intercept. The y intercept is located at (0, 20). 
To find the slope, take two points. Let's use (1,40) and (2,60).
Use the slope formula: (y1 - y2)/(x1 - x2)
(60-40)/(2-1)= 20/1= 20.
The slope is 20, the equation is: y = 20x + 20.
Now plug 10 into x: 
y = 20(10) + 20
y = 220 
Your answer is 220.

What is the average rate of change of f over the interval -4≤x≤5
Ira Lisetskai [31]

The average rate of change over the interval is 2/9

<h3>How to determine the average rate of change?</h3>

The interval is given as:

-4 ≤ x ≤ 5

From the table, we have:

f(5) = 4

f(-4) = 2

The average rate of change is then calculated as:

m = \frac{f(5) - f(-4)}{5 --4}

This gives

m = \frac{4 - 2}{5 +4}

Evaluate

m = \frac{2}{9}

Hence, the average rate of change over the interval is 2/9
