A line contains points (6,-3) and (3,1) . When the line is reflected across the y-axis what are the 2 new points

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

The first point (6, -3) becomes (-6, -3) when reflected across the y-axis.
The second point (3, 1) becomes (-3, 1) when reflected across the y-axis.
