When a point is reflected across the y-axis, the x-coordinate changes sign while the y-coordinate remains the same.
For point K with coordinates (6, 3):
- The new x-coordinate will be -6 (change the sign of 6).
- The y-coordinate remains the same, which is 3.
Thus, the new coordinates for the reflected point K will be (-6, 3).
So the correct response is:
(−6, 3)
