You can put this solution on YOUR website!
You could sit and pick an x, then find the y and plot it but the
fastest way to graph with this form is to find your x and y interepts.
The x intercept occurs when y=0.
3x-y=-10
3x-0=-10
3x=-10
x=-10%2F3
First point is (-10/3,0).
The y intercept occurs when x=0.
3x-y=-10
3%280%29-y=-10
-y=-10
y=10
Second point is (0,10).
Graph those 2 points. You only need two points to define a line.

Then draw the line that goes through those two points.
