Exploring Constant Rate of Change

The video tutorial covers the concept of constant rate of change, explaining how it can be identified and calculated in various contexts. It begins with a theoretical overview, followed by practical examples using programming costs and car washing fundraisers. The tutorial demonstrates how to use tables and graphs to find and analyze constant rates, emphasizing the importance of unit rates in understanding proportional relationships.

What is a constant rate of change?

• A rate that varies over time

• A rate that describes how one quantity changes in relation to another and remains the same

• A rate that only applies to non-linear relationships

• A rate that changes randomly
