Point K is on figure D has the coordinates (6, 3). If it is reflected across the y-axis, what would the new coordinates be for the reflected point K?
1. (-3, 6)
2. (6, -3)
3. (-6, 3)
4. (3, 6)
The reflection across the y-axis negates the x-coordinate of a point while keeping the y-coordinate the same.
Therefore, the new coordinates for the reflected point K would be (-6, 3).
The correct answer is option 3.
