Question

A line passes through the points (p, a) and (p, –a) where p and a are real numbers and p ≠ 0. Describe each of the following. Explain your reasoning. slope of the line equation of the line y-intercept slope of a line perpendicular to the given line

Answer 1

The line would be x = p

Explanation:

Since both points have p as the x-coordinate, this means that the line is vertical. All vertical lines can be written as x = (a number). Then you can use the p as the number.
