## Graphs and Graphing Utilities

1.1 - Graphs and Graphing Utilities TI-82 There are several kinds of graphs that the TI-82 or TI-83 will do, but they are accessed from the same key. The [y=] key and the [2nd] [y=] or [StatPlot] key. The two major kinds of plots may cause confusion when mixed, so it is best to turn off all unnecessary plots before trying to graph an equation. To turn off all statistical plots, hit [StatPlot] and choose option 4 - PlotsOff. Hit enter to finish the command. To turn off a regular plot, one can either hit [Clear] while on an equation, or arrow to the left so that the cursor is on the equal sign, and press enter to toggle the display of that equation.
