Presentations Continue; What's a Rate of Change?

Student group presentations continued today after a brief review over the lesson on the rate of change. This information can be found in Lesson 4.4 of your book (on page 229). Simply put, the rate of change is defined as the change in the y values divided by the change in the x values. We will learn later that this is another way to determine the slope. The unique thing about the rate of change is that it often relates to a real-world problem, and because it does, it requires you to include labels. Common examples of rates of change include velocity (miles per hour) and cost per item.
