Question

find an equation of the vertical line through (0, -4). the equation is \\(\square\\). (type your answer in standard form.)

Explanation:

Step1: Recall vertical line form

Vertical lines have the form $x = a$, where $a$ is the x-coordinate of all points on the line.

Step2: Identify x-coordinate of the point

The given point is $(0, -4)$, so its x-coordinate is $0$.

Step3: Write the equation

Substitute $a=0$ into the vertical line form.

Answer:

$x = 0$
