Question about Texas Instruments TI-84 Plus Calculator

When I want to plot an equation and go to the Y= button the plot1 is highlighted and I can't figure out how to unhighlight it.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

SOURCE: how do you plot two liner equations on a ti-84?

I use one of the graphing APPS or do through a program. I have a users manual for TI 84 silver Edition that shows you how to archive\ unarchive to run programs here at this site. Usually, I tell people to just forget about the programs and use the simple concepts so, that they could operate their calculator better. But, if you notice in those program are actually more powerful than the programs you get on the web, because I wrote them to be flawless, or I only used programs that I knew would not clash and were very well written. Won't y1=(2/5)x-(11/5) and -3x+8 work?

y1=(2/5)x-(11/5) and -3x+8

SOURCE: I am trying to drive a prediction equation. but

I assume you know how to enter data in your calculator. The keystrokes in the following pertain to TI92/92Plus/ Voyage 200 PLT. The main differences with the TI89/Ti89 Titanium is that the function keys F6,F7,F8 are not accessed directly but by the key sequences [2nd][F1], [2nd][F2], and [2nd][F3] respectively

1. CLEAN THE SLATE (so to speak) and ENTER DATA

In Home folder run F6: NewProb to reset the configuration.

Press Apps, and select 6: data/Matrix editor. Select a new data set

Give it a name: here testing.

Press OK/ENTER, The data entry screen opens, enter your values.

When you finish press F2.PlotSetUp.

2. Statistical plot setup and scatter plot drawing

.

Press F1:define to configure Plot1. Choose Scatter, then choose a mark for the data point. I select 5:Dot. and press [ENTER

Select the data column X=c1, Y=c2

Press
ENTER to save configuration. Press [CTRL] [GRAPH] On my TI92 the CTRL
key is the [Diamond] key. On the following graph I changed the mark to a
cross to see the data point better. I also played with the window
dimension. You can also do that with ZoomStat. The graph remind me of a
parabola (I know I chose the exact values)

3. STATISTICAL CALC. AND REGRESSION ANALYSES.

Now we have to find the equation that fits these data best.

You
press APPS 6:Data/ Matrix editor but you select current to return to
your data set. You are taken to the data entry editor (Figure 3 above).
In that screen Press F5:Calc to edit the type of statistics you want

On
first line select the type of regression model : Linear Regression, QuadReg quadratic regression (or anything else available) X is from column1, Y is
from column 2. Store RegEQ The regression equation in say Y1(x)

Press ENTER to save to get the Regression Equation. Here it is

As you can see I cheated: a perfect parabola. R^2 =1.

And here the best fit represented on same graph as the statistical data

Usually you have to try different regression models, until you find the one that fits best the experimental data.

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

Hey. I had the exact same problem as you and all I could do was reset the settings to the default settings on the calculator. All you have to do is turn the calculator on, his 2nd (it should say mem right above it). Then click reset then RAM.

Press the Y= button.

There are several possibilities:

1) Scroll through all equations, Y1 through Y9 and Y0. Make sure they are cleared.

2) The equation you typed in is not entered correctly.

3) Make sure Plot 1, Plot 2, and Plot 3 are NOT highlighted.

Hello,

1.Press [MODE], scroll to set**Func**tion graphing mode.

2.Press [STAT] [5:SetUpEditor], command is pasted in home screen. Press [ENTER]. Screen displays Done. This clears old values in lists

3. Press [STAT][1:Edit] to enter data.

Press [ENTER] after each number. Cursor moves to next row. After finishing the data of Listt L1, use arrow right and UP to the head of list L2. Enter the values in list L2. Press Enter after last element.

4. Press [Y=] to display Y= editor. Clear function Y1 and all functions or remove highlight from the = in Y2, Y3, etc.

5.Press [2nd][STATPLOT]1 to select 1:Plot1

The blinking cursor on ON means graph will be drawn. Type chosen is Scatter plot. Mark chosen is a dot.

Press [ZOOM][9:ZoomStat]

If you think that the curve look like a straight line you can try to do a linear regression.

Press [STAT] Arrow right to highlight [CALC]

Select [4: LinReg(ax+b)]

LinReg(ax+b) echoes on run screen. Press [2nd] L1 Press comma, Press [2nd] L2 press comma Press [VARS] Arrow right to select [Y:VARs][1:Function] [ENTER][1:Y1]

ENTER

That is the equation for the linear regression. As you see eqaution has been saved in Y1. Press [GRAPH] to get the data and the regression curve drawn on same graph.

Hope it helps.

turn off the stat plot by pressing 2nd button and then the STAT PLOT button.

This probably means you have a statistics variable set to on in your graphing screen. Press . If you see one, or more of the plots at the top highlighted you should turn them off.

To turn them off use the until**Plot1** is highlighted. Use the if needed to move to a highlighted plot. Press .
