Answer
First, graph the equation \[3x+y=0\].
Before plotting the graph in the graphing utility, the equation must be in standard form \[y=mx+c\].
Rearranging the terms so that y is isolated:
\[\begin{align}
& 3x+y=0 \\
& y=-3x \\
\end{align}\]
Now, use the steps defined below to plot the graph by TI83.
Step 1:
Select [Y=] screen to enter the equation \[y=-3x\].
Step 2:
Select [GRAPH] screen to plot the graph on the screen.
