A line segment has endpoints (1, 1) and (4, 4). Demonstrating the properties of reflections across the y-axis, what are the reflected endpoints? (1 point)
O (-1, 1) and (-4, 4)
O (1, - 1) and (4, - 4)
O (-1, 1) and (4, 4)
◎ （-1，-1） and （-4， -4）
The correct answer is (O) (-1, 1) and (-4, 4).
When reflecting across the y-axis, the x-coordinates of the points are negated while the y-coordinates remain the same. Therefore, the reflected endpoints would be (-1, 1) and (-4, 4).
