How do I find a system of inequalities for a polygon that i drew in a coordinate plane?

If I drew a decagon in a coordinate plane, with the verticies: (11,14) (15,15) (18,12) (19,9) (18,6) (15,4) (11,4) (8,6) (7,9) (8,12), how would I find a system of inequalities corresponding to the polygon that I drew?

The intersection of all of those inequalities should give you the polygon.
