Since 2x+y>4 you get y>4-2x. Then you draw the line y=4-2x then you are interested in everything above the line not including it since it is y>4-2x so it is a dashed line. You need to shade the side that satifies the inequality and since it is every pair (x, y) where y>4-2x, you need to shade everything above the line which is the side that does not include the origin. So the answer is C.
