Answer:
The slope of line formed by given two points is undefined as the denominator becomes zero.
Explanation:
Given points are:
(2,4) and (2,-2)
Here

Slope is defined as the steepness of a line in the plane.
It is denoted by m and is given by the formula:

Putting the values we get

The slope of line formed by given two points is undefined as the denominator becomes zero.
