Explanation & Answer

Thank you for the opportunity to help you with your question!

2y > x-2

We observe that this is a strict inequality. Origin (0,0) is a point in the feasible region.

Hence first and fourth figure are ruled out.

Second figure includes the points (0,-1) and (2,0) which is not possible since -2= -2 and not -2>-2

or 0 =0 and not 0 > 0

Third figure excludes (0,-1) and (2,0)  which ensures strict inequality. 

Hence the third figure (with dashed line in the boundary or edge) is the graph for the inequality

 2y > x-2 

Please let me know if you need any clarification. I'm always happy to answer your questions.
