A line contains the points (6,−3) and (3, 1) . When this line is reflected across the y -axis, what are the two new points?(1 point)
To reflect a point across the y-axis, we change the sign of the x-coordinate while keeping the y-coordinate the same.
Given the points (6, -3) and (3, 1), when reflected across the y-axis, the x-coordinate of each point changes sign:
- For the point (6, -3), the new point after reflection is (-6, -3).
- For the point (3, 1), the new point after reflection is (-3, 1).
Therefore, the two new points after reflecting the line across the y-axis are (-6, -3) and (-3, 1).
