Press [MODE][3][2]. In first column enter known x-coordinates (1 and 5), in second known y-coordinates (2 and 6). The solution you are looking for is in form Y=A+B*X where X=3. Your calculator computes A and B after you enter data. To calculate Y (which is equal to A+B*3 press [SHIFT][1][7][1][+][SHIFT][1][7][2][*][3][=]. The result should be 4.

How do i get the ee to work on my casio fx-115es plus?


What you call the EE ((entering power of 10 exponents) is done with the help of the key at the bottom right, and marked [x10^X].
To enter 6.02x10^23, you do as follows
6.02 [x10^X]23. When you use that short-cut key, no 10 should appear on the command line. See screen capture.

How do i get l1 l2 l3 charts up


L1, L2, L3?
If you are doing statistics, Set MODE to 3. Stat.
Choose 1-Var or any regression model. If you press 1-var you will have two lists x and frequency.
For any regression model you have 3 lists x, y, and Freq(uency).
L1, L2, L3, are list names in the TI 83/84 Plus and the Casio graphing calculators.
However I have no idea what getting the charts up mean.
I hope it helps

How do you do turn on diagnostics with a casio fx-9750g plus?


You don't do anything for the Casios.. If the correlation and determination coefficients have a meaning in the regression model (such as linear regression) they will be calculated and displayed automatically on the same screen where the regression equation is displayed. However if the regression model has no such coefficients nothing will be displayed.

Hi, i have a casio fx-82au plus, and it gives me the wrong answer when i press -X^2(X is any number. it'll give me -X. how can i fix this??


If you want to square a negative number, you should enclose it in parentheses then raise it to the 2nd power.
-5^2 =-25 .Priority to squaring ahead of negating
(-5)^2=25 .Priority to parentheses before squaring
