Step-by-step explanation:
Hey there!
x1= -2 and y1=5
x2=-2 and y2=0
The slope of a line having two lines are;
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{0 - 5}{ - 2 + 2} [/tex]
Simplify it.
[tex]m = \frac{ - 5}{0} [/tex]
= undefined. [ Because something divided by 0 is undefined].
Therefore, the slope is undefined.
Hope it helps...
