Question

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

Explanation:

Step1: Identify the line type

The line is vertical, so its equation 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 \( x = 200 \) (since it is at \( x = 200 \) on the x - axis). So the equation of the line is \( x = 200 \).

Answer:

\( x = 200 \)
