Question Analysis
This question tests the student's ability to determine the slope of a line given two points. The points and lie on a vertical line, and the slope of a vertical line is undefined.

Key Concept Explanation
For a vertical line, the x-coordinates of any two points are the same, resulting in a change in x (Δx) of zero. The slope formula results in division by zero, making the slope undefined.

Step-by-step Solution
1. Identify the coordinates of the points:
