LinP 3.6

Description:
____________

	This program performs linear regression on a set of points, and, unlike the LinR function, draws the approximated line AND points.  This helps when you want to see visually how the line fits the points.  Exponential, logarithmic, power, and logistic regression graphing tools are here in ExpP, LogP, PwrP, and LgstP.
	This is my last version of LinP.  Coming up next instead is a combined, full-featured regression prog.

New Features:
_____________

	I cut down the size here by about 157 bytes, much of it thanks to TI83_Basic_Wizard's basic optimization guide.  It also now draws the line as an equation, so if you decide to change the zoom (even though it automatically sizes and centers itself on the points), the line won't disappear.  Because of this, line equation y1 will be modified.
	
Number Entry:
_____________

	When prompted for a number for the x or y list, enter the number with the keypad.  If you want to enter more numbers in the current list, then press enter twice.  If you are done entering numbers for that list, instead press enter, then exit.  Remember, you must have the same number of x and y's.  If you don't understand this, e-mail me and I'll explain better.

Warnings:
_________
	
	After this program is run, it will leave on and modify plot 1, and equation y1, possibly change the zoom, destroy xStat and yStat, and destroy vars I and T.  Sorry, but it's not possible for it to not modify the plot and y1.
	I am not responsible for any damage resulting from use of this program......etc.  Distribute this program, modify it, even use parts of it in your own code as long as you give me credit.  If you find any bugs, etc., please e-mail me at straney@umbi.umd.edu.

Thanks a whole lot to TI83_Basic_Wizard for the optimizations.
