Where does the distance formula come from

The video tutorial explains the origin and application of the distance formula. It begins with an introduction to the importance of understanding the formula, followed by examples using a number line and coordinate plane. The tutorial then covers basic distance calculation on a number line, introduces right triangles and the Pythagorean theorem, and finally derives the distance formula using coordinate points.

Explain the importance of understanding the distance formula in different situations.
