Answer 1

Hi,
a) From the list screen press 2ND, QUIT to go to the home screen.
b) Press STAT, move the cursor to CALC and press 4 and LinReg will be displayed on the home screen
c) Press ENTER and the slope, a, will be displayed along with the y-intercept, b, and maybe some other information depending whether you have the Diagnostics turned on.
Notice that L1 and L2 are the default lists, so you don’t need to enter them after LinReg. If you put your data in other lists, you would have to enter those list names separated by a comma.

Answer 2

go to STAT --> CALC --> 4. lineReg (ax + b)

lineReg (ax + b) will appears on your graphing calculator screen, they click "2nd" and "1", then "comma" button, then click "2nd" and "2". Then "ENTER"
