You can put this solution on YOUR website!
make an input/output table
2x-3y=6
2x-3*0=6
2x=6
x=3
(3,0)
------------
2*0-3y=6
-3y=6
y=6/-3
y=-2
(0,-2)
------------------
2*6-3y=6
12-3y=6
-3y=6-12
-3y=-6
y=-6/-3
y=2
(6,2)
There you have three points.
You plot them.

You can graph it, but you can't
solve it. It is 1 equation and 2
unknowns, and thus unsolvable.
+2x+-+3y+=+6+
Add +3y+ to both sides
+3y+%2B+6+=+2x+
Subtract +6+ from both sides
+3y+=+2x+-+6+
Divide both sides by +3+
+y+=+%282%2F3%29%2Ax+-+2+
Here's the graph:
+graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+%282%2F3%29%2Ax+-+2+%29+
