Answer 1

A horizontal reflection means that we will reflect the point across the y-axis. For a point \((x, y)\), reflecting it horizontally will transform it into \((-x, y)\).

So, for the point \((-2, 1)\):

\[
(-2, 1) \rightarrow (2, 1)
\]

Thus, the correct response is:

**In the horizontal reflection, the point \((-2, 1)\) becomes \((2, 1)\).**
