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

1. The point (5, 9) when reflected across the y-axis becomes (-5, 9).
2. The point (4, -3) when reflected across the y-axis becomes (-4, -3).

Thus, the reflected endpoints are (-5, 9) and (-4, -3).

Therefore, the correct response is:
**(−5,9) and (−4,−3)**.
