Big Ideas: In a line of best fit, the slope represents the expected change in the dependent variable and the independent variable changes by one unit. This lesson builds on the students' knowledge of linear functions and slope. They can take this knowledge and apply it to statistics. The task has students analyze a line of best fit to make a prediction and to explain what the slope means in terms of the context of the problem. This builds towards students analyzing data and making predictions. Vocabulary: Line of best fit, slope, independent variable, dependent variable
