Question

write the equation of the line graphed below in simplest form.

Explanation:

Step1: Identify the line type

The graphed line is vertical, meaning it has an undefined slope and is of the form \( x = a \), where \( a \) is the x - coordinate of any point on the line.

Step2: Determine the x - coordinate

Looking at the graph, the vertical line passes through \( x = 4 \) (since it intersects the x - axis at \( x = 4 \) and is vertical, so all points on the line have an x - coordinate of 4). So the equation of the line is \( x = 4 \).

Answer:

\( x = 4 \)
