Question

give the equation for each graph.

Explanation:

Step1: Identify line type

The second graph is a vertical line. For a vertical line, all points on the line have the same x - coordinate.

Step2: Determine x - value

The vertical line passes through the point where x = 1. The equation of a vertical line is of the form x = a, where a is the x - coordinate of any point on the line.

Answer:

$x = 1$
