When a point is reflected over the y-axis, the x-coordinate changes sign while the y-coordinate remains the same.
For the point J(8, 7):
- The x-coordinate changes from 8 to -8, and the y-coordinate remains 7.
Thus, the image of J after the reflection over the y-axis is J'(-8, 7).
So, the correct response is:
J' (-8, 7).
