When reflecting a point over the x-axis, the x-coordinate remains the same while the y-coordinate changes its sign.
For the point J(8, 7):
- The x-coordinate (8) stays the same.
- The y-coordinate (7) changes to its negative (-7).
Thus, the coordinates of the image J' after the reflection over the x-axis are J'(8, -7).
The correct answer is:
**B. J'(8, -7)**.
