Answer

The line has an undefined slope (or has no slope). The line has no y-intercept. Refer to the attached image for the graph.

Work Step by Step

RECALL: The graph of $x=h$ is a vertical line whose slope is undefined (or has no slope)., and contains all the points (h, y) where y is a real number. Thus, the graph of $x=-5$ is a vertical line with undefined slope and contains all the points (-5, y) where y is a real number. This means that the points (-5, -2), (-5, 0), and (-5, 2) are all on the line $x=-5$. This line does not touch the y-axis so it has no y-intercept. Plot these points and connect them using a line. (refer to the attached image in the answer part)
