## To determine the description of the graph of the equation x = -8, let's analyze the equation and its variables.

The equation x = -8 is a simple linear equation with one variable, x, and a constant, -8. This equation indicates that the value of x is fixed at -8, regardless of the value of y.

To visualize this on a graph, you can use a piece of graph paper or create a simple coordinate system with x and y axes.

1. Choose any value for y and mark it on the y-axis. Let's say we choose y = 3.

2. Plot the corresponding point on the graph at y = 3 and x = -8, which is indicated by the equation. This point is (-8, 3).

3. Repeat the process for a few more values of y if you like. Each time, you will consistently find that the x-coordinate is always -8, while the y-coordinate can vary.

By connecting all these points, you will notice that they form a vertical line that passes through the x-coordinate -8.

Therefore, the correct description of the graph of the equation x = -8 is a vertical line through the -8, which corresponds to option c.
