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

Starting with the given points:

  1. For the point (6, -3):

    • The x-coordinate changes from 6 to -6.
    • The new point is (-6, -3).
  2. For the point (3, 1):

    • The x-coordinate changes from 3 to -3.
    • The new point is (-3, 1).

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

The correct response is: (−6,−3) and (−3, 1) left parenthesis negative 6 comma negative 3 right parenthesis and left parenthesis negative 3 comma 1 right parenthesis.
