Which statement is correct about the point (1,3) for y<2x?

Answer and explanation

Correct answer: It is not in the solution region

The governing concept is testing whether an ordered pair belongs to the solution region of a two-variable inequality. Substitute x=1 and y=3 into y<2x. The left side becomes 3, while the right side becomes 2(1)=2, so the required statement is 3<2. This statement is false. Therefore (1,3) does not satisfy the inequality and cannot lie in the solution region. It is actually on the side of the boundary line y=2x where y is greater than 2x. The boundary itself would be y=2x, and the strict symbol < excludes the boundary from the solution set. Hence option B is correct. Option A reverses the comparison, option C wrongly claims equality, and option D is false because the point’s x-coordinate is 1 rather than 0.
