Answer:
The slope of the line is un-defined
Step-by-step explanation:
Explanation:-
Given points are ( -10 , 4) and (-10 ,8)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]m = \frac{8-4 }{-10-(-10}) = \frac{4}{-10+10} = \frac{4}{0}[/tex]
m = ∞
The slope of the line is un-defined
