Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

How do I graph a set of points on a TI-84 Plus Silver Edition? I see how to graph a "y" point value but not (x,y)

First click on the Y= button and enter an eqation or goto stat and hit enter and type the points. Afterwards goto Y= then hit plot1 so it is highlighted and hit zoom and then zoomstat and you will have grphed your points.

Try to set the Zoom window to ZoomStat, this way the scatter plot will display all statistical points in the data set.

You cannot have a scatter plot with just **one variable.** You need values in L1 and values in L2. If you have only one set of values you can do **1-var statistics** and plot a histogram (x-value vs. frequency).

If it is just a matter of not seeing all points, just set the zoom to **ZoomStat.**

Your data must be in two lists L1 (for x-values), and L2 (for y-values). This is the default setting. Open the STAT utility, go to the regression models. Select your model then press ENTER. The command echoes on the main screen. For example let the regression be something called **LinReg.**

On the main screen you see**LinReg**

Complete the command line as follows

**LinReg L1, L2, Y1, ENTER**

You see the statistics including the regression equation.

If you go to**Y= **Editor you will see that **Y1 **contains the regression equation.

If you have already drawn the**scatter plot** for your data, pressing GRAPH will superpose the scatter plot and the **regression curve**., and you will be able to judge the goodness of the fit.

You may have activated the dynamic graphing by running the Transfrm Application. If so, you must unload it from memory (this will not delete it from calculator)

- Press the Apps key.
- Use UpArrow (yes UpArrow) to scroll to the bottom of the list of applications.
- Point to Transfm and press ENTER.
- In new screen that displays, select the option that uninstalls Transfm.
- Do your graphs in the usual (native) environment.
