Distance on the Coordinate Plane: Key Concepts and Applications

Mr. Richards teaches how to find the distance between two points on a coordinate plane using the Pythagorean theorem and the distance formula. The lesson includes real-world applications, such as mountain biking, and provides guided examples to illustrate the concepts. Students learn to calculate distances by subtracting coordinates and applying mathematical formulas.

What is the main objective of the lesson?

• To find the distance between two points on the coordinate plane

• To learn about mountain biking

• To understand the concept of angles

• To practice drawing graphs
