Interpret Slope Using Line of Best Fit

The video tutorial explains how to identify and interpret the slope using the line of best fit. It distinguishes between exact and inexact relationships, using examples like Celsius to Fahrenheit conversion and height to wingspan predictions. The tutorial emphasizes the importance of using the line of best fit for inexact relationships, such as the correlation between study time and test scores, and warns against common misunderstandings like using individual data points to determine slope. The slope in exact relationships has a clear meaning, while in inexact relationships, it represents an expected change.

Describe how the line of best fit can be used to make predictions.
