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)

Question

• (-6, -3) and (-3, 1)
• (6, 3) and (3, - 1)
• (-6, -3) and (3, 1)
• (-6, 3) and (-3, - 1)

Answer 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)
