How do you find the equation using a graphing calculator? I referred to my ti-84 handbook but it doesn't tell you how to plot points. Then after I plot the points how do you find the equation using graphing calculator.

Thanks!
Use the regression capabilties. look in your manuals index, and you will learn how to use them.
