Coordinate Plane Concepts and Questions

Mr. Peterson introduces the coordinate plane, explaining the x-axis and y-axis, and how to label them with positive and negative numbers. He describes the four quadrants and how to identify them based on the signs of coordinates. The concept of the origin and ordered pairs is explained, with examples of how to find points on the plane. The video concludes with exercises involving character locations and calculating distances from the axes.

What is the primary purpose of the coordinate plane?

• To measure angles

• To plot points in a two-dimensional space
