Proportional Tables and Equations Challenge

This video tutorial explores proportional relationships, focusing on how numbers relate through ratios and proportions. It covers the use of tables and equations to represent these relationships, explains the concepts of slope and unit rate, and demonstrates how to analyze ordered pairs. The video includes practice problems to reinforce understanding and prepares viewers for graphing these relationships in future lessons.

What does it mean when numbers are in a proportional relationship?

• They reduce down to the same ratio.

• They add up to the same total.

• They are always different.

• They are always equal.
