To reflect a point across the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same.

For the point (6, -3), reflecting it across the y-axis gives:

  • \(x\): from 6 to -6
  • \(y\): stays -3

This results in the point (-6, -3).

For the point (3, 1), reflecting it across the y-axis gives:

  • \(x\): from 3 to -3
  • \(y\): stays 1

This results in the point (-3, 1).

So, the two new points after reflecting across the y-axis are: (-6, -3) and (-3, 1).

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