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)
To reflect a point across the y-axis, we change its x-coordinate to its opposite value while keeping the y-coordinate the same.
The original endpoints are (1, 1) and (4, 4).
To reflect (1, 1) across the y-axis, we change the x-coordinate to its opposite value: (-1, 1).
To reflect (4, 4) across the y-axis, we change the x-coordinate to its opposite value: (-4, 4).
Therefore, the reflected endpoints are (-1, 1) and (-4, 4).
