Re: Please Help--Programming difficulties on the TI-92
[Prev][Next][Index][Thread]
You're using a TI-92, right? The ability to find the slope and
y-intercept is probably built-in, since even the TI-81 can do this.
Go to [STAT] (or TI-92 equivalent), plug in two points. Calculate a
linear regression.
