You can put this solution on YOUR website! Graph 3x+2y > 5 to get
The shaded region in green above represents all of the points that satisfy 3x+2y > 5
The three points (2,5), (3, 7) and (4, 8) all lie in this green shaded region.
You can show this algebraically.
Check:
3x+2y > 5
3(2)+2(5) > 5 ... Plug in (2,5)
6 + 10 > 5
16 > 5 ... which is TRUE. So (2,5) is a solution.
----------------------------------------------
3x+2y > 5
3(3)+2(6) > 5 ... Plug in (3,6)
9 + 12 > 5
21 > 5 ... which is TRUE. So (3,6) is a solution.
----------------------------------------------
3x+2y > 5
3(4)+2(8) > 5 ... Plug in (4,8)
12 + 16 > 5
28 > 5 ... which is TRUE. So (4,8) is a solution.
