To find the length of segment $\overline{AB}$, we subtract the coordinate of point A from the coordinate of point B.

Given that:

• The coordinate of point A is 26.
• The coordinate of point B is 65.

The length of $\overline{AB}$ is:

$AB = |B - A| = |65 - 26| = 39$

Thus, the length of $\overline{AB}$ is 39 units.

1. How do we calculate the length of a segment when the points are negative?
2. What is the distance formula for points in a 2D plane?
3. How would the process change if the points were given as decimals?
4. What if the points A and B represented coordinates on a number line in the opposite direction?

Tip: Always use absolute values when finding the length of a segment to ensure the distance is positive.
