To reflect a point horizontally, we change the sign of the x-coordinate while keeping the y-coordinate the same.
The point given is (-2, 1).
- The reflection results in the x-coordinate changing from -2 to 2, while the y-coordinate remains 1.
Therefore, the reflection of the point (-2, 1) is (2, 1).
So the correct answer is:
• In the horizontal reflection, the point (-2, 1) becomes (2, 1).
