Question

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

Explanation:

Step1: Identify coordinates of A and B

From the number line, point A is at \( x = 2 \) and point B is at \( x = 9 \).

Step2: Calculate the length of segment AB

The length of a segment between two points \( x_1 \) and \( x_2 \) on a number line is given by \( |x_2 - x_1| \). Substituting \( x_1 = 2 \) and \( x_2 = 9 \), we get \( |9 - 2| = 7 \).

Answer:
