Exploring Ordered Pairs and Relations

The video tutorial covers the basics of ordered pairs and relations, starting with an introduction to the coordinate plane and its vocabulary. It explains how to identify and name ordered pairs, followed by instructions on graphing them. The tutorial concludes with a discussion on relations, including definitions and examples, and how to express them as tables and graphs. The video also covers the concepts of domain and range, providing examples to illustrate these ideas.
