    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!
