Answer:
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
From the question the points are
(5,−3) and (5, 8)
The slope is
[tex]m = \frac{8 - - 3}{5 - 5} = \frac{8 + 3}{5 - 5} = \frac{8}{0} \\ [/tex]
Since every number divided by zero is undefined the slope of the line is also undefined.
Hope this helps you
