Answer 1

When reflecting a point over the y-axis, the x-coordinate of the point changes sign, while the y-coordinate remains the same.

For the point P(−2, 7):
- The x-coordinate is -2, which will become 2 (its opposite).
- The y-coordinate remains 7.

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

The coordinate of P′ is **P′(2, 7)**.
