Answer:
Undefined
Step-by-step explanation:
Use the following formula to solve for slope:
[tex]\frac{y_2-y_1}{x_2-x_1} =m[/tex]
[tex]m=\frac{(-1)-2}{8-8}[/tex]
[tex]m=\frac{-3}{0}[/tex]
The equation is not a function and therefore the slope is undefined because there are multiple y values for a single x value.
