Answer: (c) y>-1/3 * x + 2
Explanation: The area is shaded *above* the border line which corresponds to the ">" sign. The border line is dashed, ie., it does not belong to the solution space, therefore there is no "=" sign. The slope is negative and 1/3 (can be seen in the graph). The y-intercept is 2, which corresponds to the "+2" term of the inequality in (c).
