Answer
The following image is the graph of $y=-2x$.
Work Step by Step
Input two arbitrary values of x into the equation $y=-2x$ to obtain two ordered pairs.
For example:
When $x=1$, $y=-2$, and thus one ordered pair would be $(1,-2)$.
When $x=-1$, $y=2$, and thus another ordered pair would be $(-1,2)$.
The two points are joined together by a straight line in order to graph the equation.
