*The command line should look like this on the screen: LinReg(ax+b) L1, L2, Y1. Press “ENTER” Copy the data to your scatterplot data sheet. 5. Graph the line of best fit. Press “ZOOM” and scroll down to “ZoomStat” Press “ENTER” Make sure your points coincide with the points on the graph. Draw the line that’s on the calculator ...
SCATTERPLOTS AND LINES OF BEST FIT
Adjust the window to fit the data. Turn on the scatterplot function. View the graph. How does the calculator’s graph of the scatterplot compare to your graph in #1? Determine the regression equation for the line of best fit. Store the equation in the Y= Editor of the calculator. (This is only an example screen.)

Your calculator can find the equation of the line of best fit through a process called linear regression. This is a statistical calculation, so the command is found in the STAT CALC menu 4:LinReg(ax+b). Note that the calculator uses a for the slope and b for the y-intercept. Hit ENTER to bring the command to the home screen and ENTER again to ...
