Description
In this lesson, students informally fit a line to data by drawing a line that describes a linear pattern in a scatter plot and then use their lines to make predictions. They determine the equation of the line and informally analyze different lines fit to the same data. This lesson begins developing the foundation for finding an objective way to judge how well a line fits the trend in a scatter plot and the notion of a best-fit line in Algebra I.
