How to Type Table Values Into a Graphing Calculator

The TI-83 graphing calculator can be used to plot simple algebraic shapes such as lines and parabolas with an equation or a table of values. Tapping into the latter functionality requires setting up a statistics table with two columns -- one for x-axis values and one for y-axis values. After setting it up, you need only enable statistics plotting, set up coordinates corresponding to the graph's range and then graph it.

Instructions

1

Press the "STAT" button and then hit "ENTER."

2

Enter the first x-axis value, press the down arrow, enter the second x-axis value and continue doing this until all the x-axis values have been submitted. Press the right arrow key, enter the first y-axis value, press the down arrow, enter the second y-axis value and continue doing this until all the y-axis values have been submitted.

3

Press the "2ND" button and then the "Y=" button. Press "ENTER" twice.

4

Enter a number corresponding to the minimum x-axis coordinate that the graph should cover. Press the down arrow and then enter the number corresponding to the maximum x-axis coordinate that the graph should cover. Press the down arrow twice, enter the y-axis minimum, press the down arrow again and enter the y-axis maximum.

5

Press the "GRAPH" key.
