Math · Algebra · Easy · Answer it here, explanation included.

The point  in the xy-plane is a solution to which of the following systems of inequalities?

ExplanationShow

Choice A is correct. The given point, , is located in the first quadrant in the xy-plane. The system of inequalities in choice A represents all the points in the first quadrant in the xy-plane. Therefore,  is a solution to the system of inequalities in choice A.

Alternate approach: Substituting for in the first inequality in choice A, , yields , which is true. Substituting for in the second inequality in choice A, , yields , which is true. Since the coordinates of the point  make the inequalities and  true, the point  is a solution to the system of inequalities consisting of and .

Choice B is incorrect. This system of inequalities represents all the points in the fourth quadrant, not the first quadrant, in the xy-plane.

Choice C is incorrect. This system of inequalities represents all the points in the second quadrant, not the first quadrant, in the xy-plane.

Choice D is incorrect. This system of inequalities represents all the points in the third quadrant, not the first quadrant, in the xy-plane.
