I need TI-85 graphing calculator help. Reset it to the factory settings? And then how do I graph the equation of a line, for example y=2/3x + 6?

To reset the TI-85 factory settings you would have to use
the following
keystrokes:

• 2nd


• +


• F3


• F1


• F4

F3
is used to indicate that you want to reset. F1 is to choose
everything and F4 is to choose yes for the prompt which
asks if you actually want to reset everything.

This would
clear all stored data, functions, programs and any custom settings you may have made.
The configuration of the calculator is now as it was when you bought
it.

To graph the equation of a line like y = 2/3x +
6

First press GRAPH. Next
press F1 to select <y(x) =>. Then you enter
the equation you want to graph. You would have to use the keystrokes
(, 2,
divide, 3,
), divide,
x-VAR, +,
6

Once the equation is
entered, you could entering a RANGE for the x and y values
that have to be traced or try out the ZOOM and the
TRACE options to view your graph with more
clarity
