Lesson Plan

Confirm that a scatter plot suggests a linear association before fitting a line

Estimate a line of fit by eye, balancing points above and below the line

Find the equation of a fitted line both by an informal two-point method and by technology least-squares regression

Use a fitted line equation to make predictions, understanding it as a trend summary that need not pass through every point
