P′(2,7)

Answer 1

When a point \((x, y)\) is reflected over the y-axis, the x-coordinate changes sign while the y-coordinate remains the same.

For the point \(P(-2, 7)\):

- The x-coordinate \(-2\) becomes \(2\).
- The y-coordinate \(7\) remains \(7\).

Thus, the reflected point \(P'\) is \(P'(2, 7)\).

So, the correct response is:
\(P′(2, 7)\)
