We have a equation of a line in the form:
[tex]-3x-6y=0[/tex]
This goes through the point (0,0).
With another point, we can graph the line.
For example, for x=2, we have:
[tex]\begin{gathered} -3(2)-6y=0 \\ -6-6y=0 \\ -6y=6 \\ y=-1 \end{gathered}[/tex]
So the point (2,-1) belongs to the line.
We can graph the line passing through those points:
