Question

find an equation of the vertical line through (-4,2). the equation is y = 2. (type your answer in standard form.)

Explanation:

Step1: Recall equation of vertical line

The equation of a vertical line passing through the point $(x_0,y_0)$ is of the form $x = x_0$.

Step2: Identify the x - coordinate

Given the point $(-4,2)$, the x - coordinate is $x_0=-4$. So the equation of the vertical line is $x=-4$.

Answer:

$x = - 4$
