To find the reflected endpoints of a line segment across the y-axis, we need to change the x-coordinates of the endpoints while keeping the y-coordinates the same.

The original endpoints of the line segment are (1, 1) and (4, 4).

  1. Reflected point of (1, 1):

    • The x-coordinate changes from 1 to -1, so the reflected point is (-1, 1).
  2. Reflected point of (4, 4):

    • The x-coordinate changes from 4 to -4, so the reflected point is (-4, 4).

Thus, the reflected endpoints are (-1, 1) and (-4, 4).

The correct response is: (−1, 1) and (−4, 4).
