When a point 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 of P is -2, which becomes 2 after reflection.
- The y-coordinate remains 7.
Therefore, the coordinates of P′ after reflection over the y-axis are P′(2,7).
So the correct response is:
**P′(2,7)**.
For the point P(−2,7):
- The x-coordinate of P is -2, which becomes 2 after reflection.
- The y-coordinate remains 7.
Therefore, the coordinates of P′ after reflection over the y-axis are P′(2,7).
So the correct response is:
**P′(2,7)**.
