You can put this solution on YOUR website!
-x-2y=6is a linear equation. (You could call it a linear function too. Given a value for x, you can calculate the one value for y corresponding to that value of x).
Its graph is a straight line.
All you need to do is plot 2 points and connect them with a straight line.
You want to chose two points that are easy to calculate and make graphing easy.
In this case, I would pick x=0 for one point and y=0 for the other.
For x=0, -2y=6 --> y=-3, giving you the point (0,-3).
For y=0, -x=6 --> x=-6, giving you the point (-6,0).
Those points are easy to calculate, easy to plot, and reasonably spaced to allow you to draw a good line.
Then you just have to draw your x-axis and y-axis so that your points appear sort of in the middle of the graph.
