Identify the distance between two points

The video tutorial covers drawing triangles and setting up points, using the Pythagorean theorem to find lengths, and comparing counting intervals with algebraic methods for calculating distance. It explains differentiating coordinate points and deriving the distance formula, followed by applying the formula with examples and calculations.

What is the distance formula and how is it derived from the Pythagorean theorem?

How would you calculate the distance between the points (5, -3) and (2, -1)?
