Start with the given system of inequalities
2x%2B3y%3E6



In order to graph this system of inequalities, we need to graph each inequality one at a time.

So lets graph the first inequality

In order to graph 2x%2B3y%3E6 we need to graph the equation 2x%2B3y=6 (just replace the inequality sign with an equal sign). So lets graph the line 2x%2B3y=6 (note: if you need help with graphing, check out this solver)
graph%28+400%2C+300%2C+-10%2C+10%2C+-10%2C+10%2C%286-2%2Ax%29%2F3%29 graph of 2x%2B3y=6
Now lets pick a test point, say (0,0) (any point will work, but this point is the easiest to work with), and evaluate the inequality 2x%2B3y%3E6
2%280%29%2B3%280%29%3E6 Plug in x=0, y=0

0%3E6 Simplify


Since this inequality is not true, we shade the entire region that doesn't contain (0,0)



Here is the graph of 2x%2B3y%3E6 with the graph of the line(2x%2B3y=6) in red and the shaded region in green
(note: The red line should be a dashed line since it is not included in the region. Since the inequalityis a > sign, it tells us not to include the boundaries.)
