To find the reflected endpoints of the line segment with endpoints (1, 1) and (4, 4) across the y-axis, we need to negate the x-coordinates of the points while keeping the y-coordinates the same.
For the point (1, 1):
- The reflection across the y-axis will be (-1, 1).
For the point (4, 4):
- The reflection across the y-axis will be (-4, 4).
Thus, the reflected endpoints are (-1, 1) and (-4, 4).
The correct response is: (−1, 1) and (−4, 4)
