Tim has to write two papers worth 50 points each. To pass, he has to get at least 45% of the total points. However, scoring less than 30% of the points on either paper, even if his total for both papers is above 45%, will result in him failing. Which graph represents the region in which Tim fails? (Assume that he scores x points on paper A and y points on paper B.)
