Question

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

Explanation:

Step1: Recall the form of a vertical line equation

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

Step2: Identify the \(x -\)coordinate

Looking at the graph, the line passes through points where \(x = 3\) (for example, \((3,0)\), \((3,1)\), \((3, - 1)\) etc.).

Answer:

\(x = 3\)
