(4) Listen What notation is used to represent the distance from point \( A \) to \( B \) ? \( \overline{A B} \) \( O A-B \) O \( \overleftrightarrow{A B} \) \( O A B \)

The correct notation to represent the distance from point \( A \) to point \( B \) is \( \overline{A B} \). Here's a brief explanation of the options: 1. \( \overline{A B} \): This notation indicates the line segment connecting points \( A \) and \( B \), which represents the distance between them. 2. \( O A-B \): This notation is not standard for representing distance. 3. \( \overleftrightarrow{A B} \): This notation represents a line that extends infinitely in both directions through points \( A \) and \( B \), not just the distance between them. 4. \( O A B \): This notation does not represent distance and is not standard. Thus, the correct answer is \( \overline{A B} \).
