Question

y = -3
y = 3x
x = 3
x = -3

Explanation:

Step1: Analyze the line's property

A vertical line has an equation of the form \(x = a\), where \(a\) is the \(x\) - coordinate of any point on the line.

Step2: Determine the \(x\) - value

Looking at the graph, the line passes through \(x = 3\) for all \(y\) values.

Answer:

\(x = 3\)
