Re: TI-83 and the line that best fits

A linear equation is a line. If you want to fit a line to data in this
lists you have to choose LinReg(ax+b) under the STAT - CALC menu. You
then put the list containing the x variables then a comma {,} then the
list containing the y variables then if you want to graph the line,
another comma and a Y variable from the VARS - Y-VARS - Function... menu.
Press enter and you will get the equation for the graph and the equation
is also put into the y variable you chose, accessible from Y=.
What you type in looks some thin like this:
LinReg(ax+b) ,L1,L2,Y1
I hope this is of some assistance.
