3.2.0 Lesson Overview

In this lesson, you will assess the fit of various lines to data, use technology to find the line of best fit, and interpret the slope and vertical intercept of the linear model.

When you finish this lesson, you will be able to:

• Write linear models by hand from tables and graphs.
• Describe the rate of change and $y$-intercept for a linear model in everyday language.
• Use technology to find the line of best fit.

Here are the activities that will help you reach those goals:

• 3.2.1: Selecting the Best Line
• 3.2.2: Determining the Best Line That Fits the Data
  • 3.2.2: Self Check
  • 3.2.2: Additional Resources
• 3.2.3: Writing Linear Models without Technology
