Answer 1

A horizontal reflection of a point occurs when the \(y\)-coordinate remains the same, but the \(x\)-coordinate is reflected across the vertical axis (i.e., it changes sign).

For the point \((-2, 1)\):

• The \(y\)-coordinate remains \(1\).
• The \(x\)-coordinate changes from \(-2\) to \(2\).

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).
