question help: video ebook written example

Explanation:

Step1: Recall vertical - line property

A vertical line has an undefined slope and its equation is of the form $x = c$, where $c$ is a constant.

Step2: Determine the value of $c$

For a vertical line passing through the point $(3,2)$, the $x$ - coordinate of all points on the line is the same as the $x$ - coordinate of the given point. So $c = 3$.

Answer:

$x = 3$
