Question

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

Explanation:

Step1: Identify the type of line

The line is a vertical line. For a vertical line, the 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 \(x = 900\) (assuming the scale where each grid - square is 100 units and the line is at the 9th square from the origin on the positive \(x -\)axis).

Answer:

\(x = 900\)
