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.(6,−3)
2.(−6,3)
3.(−3,6)
4.(3,6)
In a reflection across the y-axis, the x-coordinate of a point is negated and the y-coordinate remains the same.
So, if point K with coordinates (6,3) is reflected across the y-axis, the new coordinates would be (-6,3).
Therefore, the correct answer is 2. (-6,3).
