ANSWER:
3
STEP-BY-STEP EXPLANATION:
We have that the formula to determine the slope is the following:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
To calculate the slope, in this case, we select the external points (-1, -6) and (3, 6) we substitute:
[tex]\begin{gathered} m=\frac{-6-6}{\:-1-3}=\frac{-12}{-4} \\ \\ m=3 \end{gathered}[/tex]
The slope of the function is 3
