Answer:
Undefined.
Explanation:
We have been given coordinates of two points on a line. We are asked to find the slope of the line using given points.
We will use slope formula to solve our given problem.
, where,
m = Slope of line,
= Difference between two y-coordinates on the line.
= Difference between two x-coordinates of the same y-coordinates.
Let
and

Substitute coordinates of the given points in slope formula:



Since the x-coordinates of both points are same which represents a vertical line, therefore, the slope of the line passing through given points is "undefined".
