2x+y<6
x>0

---------------
Note: You don't directly graph inequalities. You first of all
graph the boundary of the inequality, which is always an equality.
----
To graph x+y < 6
Graph y = -x+6 as a dashed line.
Shade the half-plane below the line.

---
To graph 2x+y< 6
Graph y = -2x+6 as a dashed line
Shade the half-plane below the line

----
The solution set is the intersection
of those two half-planes in the 1st Quadrant.
---
You only look in the 1st Quadrant because you
have x> 0 and y> 0
