Question

what is the equation of the line that passes through the point (6, -3) and has an undefined slope?

Explanation:

Step1: Recall undefined slope lines

Lines with undefined slope are vertical, with the form $x = c$, where $c$ is a constant.

Step2: Match the given point

The line passes through $(6, -3)$, so the $x$-coordinate is 6. Substitute $c=6$ into the vertical line form.

Answer:

$x = 6$
