Taking the readings from the graph

Rate of change for the given line is:

Equation for the line is:

For the point (40, 76) we can verify with the equation:

The point (40, 76) is close the line but the line doesn't pass through it.

x | y

0 | 2

2 | 6

4 | 10

6 | 14

Equation of the line is

When x=40, y will be (2×40)+2 =82

So the point should pass through (40,82) and not (40,76).
