When a point is reflected across the y-axis, the x-coordinate of the point changes sign, while the y-coordinate remains the same.
Given point K with coordinates (6, 3):
- The x-coordinate is 6, which when negated becomes -6.
- The y-coordinate remains 3.
Therefore, the new coordinates for the reflected point K will be (-6, 3).
However, since you're looking for the answer among the provided options, the correct transformation results in the coordinates:
- None of the offered responses are correct.
If you are looking for the point obtained from negative transformation across the y-axis, the potential mistake in my assessment needs your attention. If point K has its x-coordinate reflected across the y-axis, the new position should reflect the correct coordinates based on the options shared.
To confirm whether there seems to be confounding coordinates, my initial analysis leads to an honest declaration that (-6,3) is not listed, the transformation leads toward the necessity to assess (-3,6) as viable but doesn't hold correctness to spatial transformation principles.
Therefore, please verify or clarify the reflection basis if further cross-checking aligns correct from the Centre based calculation methodologies. Apologies for the oversight, and let me know how best to proceed from here!
