To find the new points after reflecting the given points across the y-axis, we change the sign of the x-coordinates while keeping the y-coordinates the same.

The original points are:

  1. (6, -3)
  2. (3, 1)

Reflecting these points across the y-axis:

  1. The reflection of (6, -3) is (-6, -3).
  2. The reflection of (3, 1) is (-3, 1).

Therefore, the new points after reflection across the y-axis are:

(−6,−3) and (−3, 1)

The correct response is: (−6,−3) and (−3, 1).
