Students will enter "life expectancy" data into lists and set up scatter plots and trace the scatter plot to select two points. Secondly, they will use the points to calculate slope and write a linear equation. Finally, they will use the Transformation Graphing App to fit the data using a linear equation in slope-intercept form and analyze the meaning of the slope and the intercept in relationship to birth year and life expectancy.
