Answer 1

The length of a line segment does not change after a reflection.

To determine the length of the original line segment with endpoints (0, 5) and (6, 5), we can use the distance formula or simply observe the coordinates:

1. Since both endpoints have the same y-coordinate (5), this line segment is horizontal.
2. The distance between the x-coordinates of the endpoints (0 and 6) is calculated as follows:
\[
\text{Length} = |x_2 - x_1| = |6 - 0| = 6 \text{ units.}
\]

When this line segment is reflected across the x-axis, the new endpoints will be (0, -5) and (6, -5), but the length remains the same.

So, the length of the line segment after it is reflected across the x-axis will still be **6 units**.

Thus, the correct response is:
**6 units**.
