Answer
The graph of $y=3x$ is shown in the following image.
Work Step by Step
The equation given is $y=3x$.
If $x=0$, then $y=0$, thus the y-intercept is $0$.
If $y=0$, then $x=0$, thus the x-intercept (or the root/zero) is $0$.
The point $(0,0)$ is both the x-intercept and the y-intercept.
Another point on the line must be found to connect with $(0,0)$ and create the graph of $y=3x$. The x-value of $1$ can be inputted in the equation to obtain $3$ as a y-value, giving the ordered pair $(1,3)$.
The points $(0,0)$ and $(1,3)$ are then connected to create the graph.
