Question

horizontal & vertical lines
what is the equation of the line?

Explanation:

Step1: Identify line type (vertical)

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

Step2: Find x - coordinate

Looking at the graph, the vertical line passes through points where \( x = 3 \) (since it aligns with \( x = 3 \) on the x - axis). So the equation is \( x = 3 \).

Answer:

\( x = 3 \)
