Question

find the length of the segment \\(overline{ab}\\). number line image the length is \\(\square\\) (type an integer or a decimal.)

Explanation:

Step1: Identify coordinates of A and B

Point A is at -9, point B is at 2.

Step2: Calculate distance between A and B

The distance between two points \( x_1 \) and \( x_2 \) on a number line is \( |x_2 - x_1| \). So, \( |2 - (-9)| = |2 + 9| = |11| = 11 \).

Answer:

11
