Answer:

-3

Explanation:

To calculate the rate of change of the function, we pick two pairs of points.

(8, -40) and (17,-67)

We use the formula below:

[tex]\begin{gathered} \text{Rate of change}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}} \\ =\frac{-67-(-40)}{17-8} \\ =\frac{-67+40}{17-8} \\ =\frac{-27}{9} \\ =-3 \end{gathered}[/tex]

The rate of change of the function is -3.
