Question

determine the equation of a vertical line that passes through each given point. sample problem (-2,1) a vertical line has the equation x = a, for points on the line of the form (a,y). given the point (-2,1), a = -2. the equation of a vertical line through the given point is x = -2. (9,-7) > enter the answer in the space provided. use numbers instead of words.

Explanation:

Step1: Recall vertical - line equation

The equation of a vertical line is $x=a$, where $(a,y)$ are points on the line.

Step2: Identify the x - coordinate

The given point is $(9, - 7)$. The x - coordinate of the point is $9$. So, $a = 9$.

Step3: Write the equation

The equation of the vertical line passing through the point $(9,-7)$ is $x = 9$.

Answer:

$x = 9$
