3.2.7 Lesson Summary

Algebra 13.2.7 Lesson Summary

Search for key terms or text.

In this lesson, you learned how to:

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

Here are the activities that helped you reach those goals:

  • 3.2.1: Selecting the Best Line
    • In this activity, you visually assessed the best line fit for data among a set of given choices. You explored bad fit, good fit, and best fit.
  • 3.2.2: Determining the Best Line That Fits the Data
    • In this activity, you distinguished between linear and nonlinear relationships in bivariate, numerical data and informally assessed the fit of a linear model. You also compared the slope and the vertical intercepts of different linear models and were able to describe the relationship between

  • 3.2.4: Assessing the Fit of a Linear Model
    • In this activity, you used technology to compute a line of best fit for data given in a table and to recognize the meaning of the slope and yy-intercept.

    • 3.2.4: Additional Resources
  • 3.2.5: Working with Fitted Lines
    • In this activity, you had an opportunity to work with fitted lines. You identified scatter plots that showed data that would best be modeled with a linear function and the line of best fit for the data provided.

After these activities, you completed the following practice:
