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 ...
