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?

Answer 1

When a point is reflected across the y-axis, the x-coordinate will change sign while the y-coordinate remains the same.

Therefore, when point K (6,3) is reflected across the y-axis, the new coordinates for the reflected point K would be (-6,3).
