To reflect a point across the y-axis, we simply change the sign of the x-coordinate while keeping the y-coordinate the same.
The original endpoints are (1,1) and (4,4).
When we reflect (1,1), the x-coordinate changes from 1 to -1 while the y-coordinate remains the same. Therefore, the reflected endpoint is (-1,1).
Similarly, when we reflect (4,4), the x-coordinate changes from 4 to -4 while the y-coordinate remains the same. Therefore, the reflected endpoint is (-4,4).
So, the correct answer is (-1,1) and (-4,4).

To reflect a point across the y-axis, we simply change the sign of the x-coordinate while keeping the y-coordinate the same.
The original points are (6,-3) and (3,1).
When we reflect (6,-3), the x-coordinate changes from 6 to -6 while the y-coordinate remains the same. Therefore, the reflected point is (-6,-3).
Similarly, when we reflect (3,1), the x-coordinate changes from 3 to -3 while the y-coordinate remains the same. Therefore, the reflected point is (-3,1).
So, the correct answer is (-6,-3) and (-3,1).
The original points are (6,-3) and (3,1).
When we reflect (6,-3), the x-coordinate changes from 6 to -6 while the y-coordinate remains the same. Therefore, the reflected point is (-6,-3).
Similarly, when we reflect (3,1), the x-coordinate changes from 3 to -3 while the y-coordinate remains the same. Therefore, the reflected point is (-3,1).
So, the correct answer is (-6,-3) and (-3,1).

When a line segment is reflected across the x-axis, the y-coordinates change sign while the x-coordinates remain the same.
The original line segment has endpoints (0,5) and (6,5).
When we reflect these points across the x-axis, the y-coordinate of (0,5) changes from 5 to -5 while the x-coordinate remains the same. Similarly, the y-coordinate of (6,5) changes from 5 to -5 while the x-coordinate remains the same.
The reflected line segment has endpoints (0,-5) and (6,-5).
To find the length of the line segment, we subtract the x-coordinates of the endpoints. In this case, the x-coordinates are the same, so the length of the line segment remains the same.
Therefore, the length of the reflected line segment is 6 units.
