To find the reflections of the 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.
The reflection of (1, 1) across the y-axis is: \[ (-1, 1) \]
The reflection of (4, 4) across the y-axis is: \[ (-4, 4) \]
Thus, the reflected endpoints are \((-1, 1)\) and \((-4, 4)\).
So the correct response is: (−1, 1) and (−4, 4).
