Question

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

Explanation:

Step1: Identify line type (vertical/horizontal)

The line is vertical (parallel to y - axis), so x - coordinate is constant.

Step2: Find x - intercept

The line passes through \( x = 100 \) (since it's at \( x = 100 \) on x - axis).

Step3: Write vertical line equation

For a vertical line, the equation is \( x = a \), where \( a \) is the x - coordinate. Here, \( a = 100 \), so equation is \( x = 100 \).

Answer:

\( x = 100 \)
