Answer 1

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

For the point \( P(-2, 7) \):
- The x-coordinate changes from \(-2\) to \(2\).
- The y-coordinate remains \(7\).

Therefore, the reflected coordinate \( P' \) is \( P'(2, 7) \).

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