When a point is reflected across the y-axis, the x-coordinate changes sign while the y-coordinate remains the same.
The coordinates of point K are (6, 3).
Reflecting this point across the y-axis:
- The x-coordinate changes from 6 to -6.
- The y-coordinate remains 3.
Thus, the new coordinates for the reflected point K are (-6, 3).
The correct response is: (−6, 3)
