When reflecting a point across the y-axis, the x-coordinate of the point changes sign, while the y-coordinate remains the same.

For the point \( (6, -3) \):

  • The reflection across the y-axis is \( (-6, -3) \).

For the point \( (3, 1) \):

  • The reflection across the y-axis is \( (-3, 1) \).

Thus, the new points after reflecting the original points across the y-axis are \( (-6, -3) \) and \( (-3, 1) \).

The correct response is:

(−6,−3) and (−3, 1).
