A horizontal reflection of a point \((x, y)\) across the y-axis changes the x-coordinate to its opposite while keeping the y-coordinate the same.
For the point \((-2, 1)\):
Thus, the new point after the horizontal reflection is \((2, 1)\).
The correct response is: In the horizontal reflection, the point \((-2,1)\) becomes \((2,1)\).
