Thread: Graphing calculator Help!

- use the table to find the equation using a graphing calculator. I have a Ti-84 plus.

Code:

Time(s)   Height

-------------------------
  0      |  450
  1      |  445
  2      |  431
  3      |  408
  4      |  375
  5      |  332
  6      |  279
  7      |  216
  8      |  143
  9      |  61

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!
