Answer explanation
Choice D is correct. For a point to be a solution to the given inequality in the xy-plane, the value of the point’s y-coordinate must be less than the value of , where is the value of the x-coordinate of the point. This is true of the point because , or . Therefore, the point is a solution to the given inequality.
Choices A, B, and C are incorrect. None of these points are a solution to the given inequality because each point’s y-coordinate is greater than the value of for the point’s x-coordinate.
