Question

look at this graph:
write the equation of the line.

Explanation:

Step1: Identify line type

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

Step2: Find x - coordinate

The vertical line passes through \( x = 4 \) (since for all points on this line, the x - value is 4, regardless of y). So the equation is \( x = 4 \).

Answer:

\( x = 4 \)
