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?

Answer 1

After reflecting the line segment across the X axis, the new endpoints will be (0,-5) and (6,-5).

To calculate the length of the new line segment, we use the distance formula:

Length = sqrt((6-0)^2 + (-5-(-5))^2)
= sqrt(6^2 + 0)
= sqrt(36)
= 6

Therefore, the length of the reflected line segment will be 6 units.
