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.

Find the Equal Sign on a Graphing Calculator
A graphing calculator helps students understand the relationship between mathematics and science. A graphing calculator is used in classes like algebra, trigonometry, calculus, physics and statistics. The calculator helps students visualize problems by entering formulas and complex equations that a regular calculator cannot do. A graphing calculator features more buttons and options than a regular calculator, so finding the "equal" sign can be difficult. Depending on what type of graphing calculator you are using, finding the "equal" sign requires you to push a series of buttons.
Instructions:
TI-82, TI-83
1. Press the "Power" button and enter a math or science problem.
2. Press the blue "2nd" and black "Math" buttons simultaneously to view the test menu.
3. Use the cursor keys to select "1." This is the "equal" button.
4. Press the blue "Enter" button to complete the equation and find the answer.
TI-85, TI-86
1. Press the "Power" button and enter an equation.
2. Press the yellow "2nd" and black "2" buttons on the graphing calculator. This will display the test menu.
3. Press the cursor buttons until the "=" sign is highlighted.
4. Press the "Enter" key to submit the problem and find the answer to the problem.
TI-89, TI-92
1. Press the "Power" button to turn on the graphing calculator and enter a math equation.
2. Press the orange "2nd" key along with the "5" and "8" keys at the same time.
3. Press the "5" key to select the "equal" sign. You can also press the cursor keys until the "5" is highlighted.
4. Press the blue "Enter" button to solve the problem.
