The linear regression option finds the equation of a linear equation of the form y = a + bx that best fits a set of data.First, press selecting option AEDIT to enter or change the data .

The data shown here is the points {(2,11.4) (3,17) (5,27.3) (7,36.1) (11,47.7) (13,49.9)}

Press DREG to view the regression options.

For linear regression, select option 02Rg_ax+b using or 03Reg_a+bx using

Press and select one of the linear regression options in the calculation screen. Now press followed by .

Therefore, the best-fit linear equation for this data is approximately

The regression equation can be automatically stored in the equation editor by entering the name of the equation, such as y1, after (L1,L2 as follows: choose option A and select y1 followed by .
