charts – Feasble Region for set of constraints

I’m trying to identify a feasible region for the following sets of constraints:

3A – 2B >= 0,
2A – 1B <= 200,
1A <= 150,
A,B >= 0,

I was able to solve for all constraints and found points for the following:

150,225, 150,100, and 400,600 but when I graph this, I get the feeling that their is a feasible region to the left of 1A <= 150 towards the origin. Can someone please explain where the feasible region may be? Thank you.
