2x%2B3y%3E18
3y%3E-2x%2B18
y%3E-%282%2F3%29x%2B6
First graph y=-%282%2F3%29x%2B6
graph%28300%2C300%2C-10%2C10%2C-10%2C10%2C-%282%2F3%29x%2B6%29
Then choose a point not on the line.
(0,0) is a convenient choice.
Test it in the inequality.
2%280%29%2B3%280%29%3E18
0%3E18
So (0,0) is not in the solution region.
Shade the area that doesn't contain (0,0).
