Question

your answer should take the form $x = a$ or $y = a$, whichever is appropriate.

Explanation:

Step1: Identify the line type

The given line is vertical. For a vertical line, the equation is of the form $x = a$, where $a$ is the $x$-coordinate of any point on the line.

Step2: Determine the $x$-coordinate

The vertical line passes through the point where $x = 2$. So the equation of the line is $x=2$.

Answer:

$x = 2$
