Interpreting the Y Intercept of a Line of Best Fit

The video tutorial explains how to interpret the Y intercept of a line of best fit on a scatter plot. It covers the definition of the Y intercept, provides examples from various contexts like basketball and student scores, and addresses common misunderstandings. The tutorial also discusses unrealistic data points and their implications, using examples such as heating costs. By the end, viewers should understand how to read and interpret Y intercepts in different scenarios.

Discuss an example where the Y intercept may represent an unrealistic data point.

What does a Y intercept of 121 indicate in the context of heating costs?
