Question

A line segment has endpoints (0, 5) and (6, 5). After the line segment is reflected across the x-axis, how long will it be?(1 point)

Answer 1

The length of a line segment is determined by the difference between its endpoints. In this case, the line segment has the same y-coordinate for both endpoints, which means it is horizontal. Since the line segment is reflected across the x-axis, the y-coordinate will change sign. Therefore, the new endpoints of the reflected line segment will be (0, -5) and (6, -5), which are also horizontal and have the same y-coordinate.

The length of the reflected line segment is still determined by the difference between its endpoints, which is 6 units. Therefore, the length of the reflected line segment will still be 6 units.
