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)
• (-6, -3) and (-3, 1)
• (6, 3) and (3, - 1)
• (-6, -3) and (3, 1)
• (-6, 3) and (-3, - 1)
When a point is reflected across the y-axis, the x-coordinate changes sign while the y-coordinate remains the same.
The original points are:
(6, -3)
(3, 1)
When these points are reflected across the y-axis, the x-coordinate changes sign:
(6, -3) -> (-6, -3)
(3, 1) -> (-3, 1)
Therefore, the two new points are:
(-6, -3)
(-3, 1)
The correct answer is: (-6, -3) and (-3, 1)
