Consider 2x + 3y = 6
When x = 0 , y = 2 gives (0 , 2)
When y = 0 , x = 3 gives (3 , 0)
The line 2x + 3y = 6 may now be drawn as a dotted line.
2x + 3y > 6 is a region that may be represented by a shaded area above this dotted line.
Note
The fact that the line is dotted means that the region does not include the dotted line.

2x+3y>6
2x + 3y > = 6
2x + 3y - 3y > = 6 - 3y
2x > = 6 -3y
2x – 6 > = - 3y
- 3y < = 2x – 6
-3y /- 3 < = (2x – 6) / -3
y < = (-2/3)x + 2
y < = 2 - (2/3)x
Check the following websites on graphing:

isn't it just a simple graph?
change it around to y = 2 - 2/3x
and then shade to fit the > part of the equation?
maybe i'm thinking too simple?

Keep inserting different numbers on x and y alternatively, starting from zero. The answer will come out as (x,y) as different numbers.its easy, i hope you get it right.
