Answer

The graph of the equation $~~xy = 0~~$ is a horizontal line that passes through the point $(0, 0)$ and a vertical line that passes through the point $(0,0)$ We can see the graph of the equation $~~xy = 0~~$ below.

Work Step by Step

If $~~xy=0,~~$ then $~~x=0~~$ or $~~y=0$ The graph of the equation $~~xy = 0~~$ is a horizontal line that passes through the point $(0, 0)$ and a vertical line that passes through the point $(0,0)$ Note that a horizontal line that passes through the point $(0, 0)$ is the graph of the equation $~~y=0~~$ and a vertical line that passes through the point $(0,0)$ is the graph of the equation $~~x=0$ We can see the graph of the equation $~~xy = 0~~$ below.
