Answer 1

To reflect a point across the y-axis, you change the sign of the x-coordinate while leaving the y-coordinate unchanged.

Given the endpoints of the line segment:

1. The first endpoint is (1, 1). Reflecting this across the y-axis gives us:
\[
(-1, 1)
\]

2. The second endpoint is (4, 4). Reflecting this across the y-axis gives us:
\[
(-4, 4)
\]

Thus, the reflected endpoints of the line segment are:
\[
(-1, 1) \text{ and } (-4, 4)
\]

So the correct response is:
**(−1, 1) and (−4, 4)**.
