in the graph below line k y equals negative X makes a 45° angle with the x - 4 y axes

Because we are reflection the point (2, 5) about the line k: y = -x
so the x and y values change positions and become negative, the firs reflection would be (-5, -2)
and then reflection on the x axis gives us (-5, 2)
So the final answer would be the third option, (-5, 2)
