When trying to perform a linear regression, my fx-9750II calculator doesn't give me the option of graphing once I put the info into lists. The options it gives me are "SRT-A", "SRT-D", "TOP", and "BTM", but no "GRAPH". I don't know what I'm doing wrong.

Any help, advice or links you could provide would be a great help. Thank you.

It seems that you are having trouble finding the graphing option on your fx-9750II calculator while trying to perform linear regression.

To help you troubleshoot the issue, let's go through a step-by-step process:

1. Enter the data: Make sure you have correctly entered your data into lists. For example, if you have x-values in List1 and y-values in List2, please make sure both lists are populated with the correct data.

2. Access the statistics menu: Press the "MODE" button, which is typically located at the top left corner of the calculator. From there, press the number corresponding to "STAT."

3. Choose the linear regression type: Within the statistics menu, locate the option for linear regression or "LinReg." It might be denoted as a sub-option under "STAT." Press the corresponding number or navigate to it using the appropriate buttons.

4. Select the lists: After choosing the linear regression type, you will need to specify the lists that contain your data. Typically, you can do this by pressing the "2nd" button (usually located above "MODE") and then pressing the number corresponding to the list. For example, if your x-values are in List1 and y-values are in List2, press "2nd" + "1" and "2nd" + "2" to select List1 and List2, respectively.

5. Calculate the regression: Once you have specified the lists, you should see an option to calculate the linear regression or "Reg." Press the corresponding button, and the calculator should perform the calculation.

Now, if you still cannot find the "GRAPH" option, it's possible that the fx-9750II calculator does not have the capability to directly graph the linear regression. In this case, you might need to manually input the regression equation into the calculator's graphing function.

If you need more specific guidance about your calculator model, I recommend referring to the user manual or online resources for your calculator. You can search for the model name and number on the manufacturer's website, as they often provide detailed instructions, tutorials, and FAQs.

I hope this helps you resolve your issue and perform the linear regression successfully. Let me know if you have any further questions!
