Answer:

B

Step-by-step explanation:

x≥0

y≥0

x+y≤2

y≤-x+2

since both y and x are greater than or equal to zero, all answers with negative coordinates are wrong

the only answer without any negative coordinates of critical points is option 3 or B, so it is right

I really like the other person's answer. It's simple and easy to verify without doing any math or graphing.

If you need the graph, then it is shown below. The idea is to graph each boundary line (all of which are solid lines) and shade the proper areas. The regions where all the shaded areas overlap is what we're after, and it is shown in blue. The vertices of the shaded region are basically the corner points. The graph was made with GeoGebra.
