Question

write the equation of the line graphed below in simplest form.

Explanation:

Step1: Identify the type of line

The 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 line passes through the point where $x = 4$. So the equation of the line is $x=4$.

Answer:

$x = 4$
