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?
a (-3,6)
b (6,-3)
c (-6,3)
d (3,6)
If a point is reflected across the y-axis, the x-coordinate is negated and the y-coordinate remains the same.
The original coordinates of point K are (6,3).
Negating the x-coordinate, we get (-6,3).
Therefore, the new coordinates for the reflected point K are (-6,3).
The correct answer is c) (-6,3).
