Answer: [tex]m=[/tex]∞
Step-by-step explanation:
The formula for calculating slope is given as:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]x_{1}=-5[/tex]
[tex]x_{2}=-5[/tex]
[tex]y_{1}=9[/tex]
[tex]y_{2}=-5[/tex]
substituting into the formula , we have
[tex]m = \frac{-5-9}{-5-(-5)}[/tex]
[tex]m = \frac{-14}{-5+5}[/tex]
[tex]m = \frac{-14}{0}[/tex]
Therefore :
[tex]m=[/tex]∞
