Answer:

undefined, stays on x so straight vertical - vertical line is undef slope

Answer: The slope is undefined  

Step-by-step explanation:

The slope of a line is calculated using the formula :

m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]x_{1}[/tex] = -7

[tex]x_{2}[/tex] = -7

[tex]y_{1}[/tex] = -7

[tex]y_{2}[/tex] = 1

Substituting the values into the formula , we have :

m = [tex]\frac{1-(-7)}{-7-(-7)}[/tex]

m = [tex]\frac{8}{0}[/tex]

m = undefined
