Answer:
Step-by-step explanation:
SLOPE FORMULA:
[tex]\rightarrow \displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN} }}[/tex]
y₂= (-8)
y₁=5
x₂=(-8)
x₁=(-8)
Solve & simplify.
[tex]\displaystyle \mathsf{\frac{(-8)-5}{(-8)-(-8)}=\frac{-13}{0}=\boxed{\mathsf{0}} }}[/tex]
Therefore, the slope is undefined.
