(−1, −1)
and (−4, −4)

Answer 1

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

The original endpoints are:

• (1, 1): The reflection across the y-axis is (-1, 1).
• (4, 4): The reflection across the y-axis is (-4, 4).

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

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