A line segment had endpoints 1,1 and 4,4 demonstrating the properties of reflections across the y axis what are the reflected endponits
To reflect a point across the y-axis, the x-coordinate changes sign while the y-coordinate remains the same.
The endpoints of the line segment are (1,1) and (4,4).
Reflecting (1,1) across the y-axis would result in (-1,1).
Reflecting (4,4) across the y-axis would result in (-4,4).
Therefore, the reflected endpoints of the line segment across the y-axis are (-1,1) and (-4,4).
