# Chapter 3 - Introduction to Graphing - 3.3 Graphing and Intercepts - 3.3 Exercise Set: 72

Refer to the graph below.

#### Work Step by Step

The graph of an equation of the form $x=h$ is a vertical line whose x-intercept is $(h,0)$. Each point on the line has an x-coordinate of $h$. Thus, the graph of $x=0$ is a vertical line whose x-intercept is $(0,0)$. Each point on the line has an x-coordinate of $0$. This means that the following points are all on the line: $(0,−2), (0,0), \text{ and } (0,2)$ Plot the three points listed above then connect them using a line to complete the graph. (Refer to the attached image in the answer part above for the graph.)
