Question

what is the equation of the vertical line through (2, 3)?

Explanation:

Step1: Recall vertical line form

Vertical lines have the equation $x = c$, where $c$ is the x-coordinate of any point on the line.

Step2: Identify x-coordinate of given point

The given point is $(2, 3)$, so its x-coordinate is 2. Substitute this into the vertical line form.
$x = 2$

Answer:

$x = 2$
