What is the slope of the line x=2?

  1. 0

  2. 1

  3. 2

  4. 3

The correct answer is: 0

The slope of a line is defined as the change in y-value over the change in x-value, also known as rise over run. In this case, the equation x=2 means that the line is a vertical line passing through the point (2,0). A vertical line has no slope because there is no change in the x-value, it remains at 2 for all points on the line. Therefore, the slope of the line x=2 is 0. Option B, C, and D all have non-zero values, making them incorrect choices for the slope.
