How do i get to the regression equation on the ti84 plus calculator. I am working on a math problem trying to view my equation once i plugged in the data
To get the regression equation on the TI-84 Plus calculator, you will need to perform linear regression using the calculator's statistical functions. Follow these steps:
1. Enter your data into the calculator. Press the STAT button, then go to Edit. Input your x-values into the first column, and the corresponding y-values into the second column.
2. Press the STAT button again and navigate to CALC. Scroll down and select "4: LinReg(ax+b)". This option is for linear regression, which will give you an equation in the form y = ax + b.
3. After selecting "4: LinReg(ax+b)", the calculator will display a screen with two lists, L1 and L2. Make sure that L1 is selected for Xlist and L2 is selected for Ylist. If your data is in different lists, select the appropriate lists.
4. Scroll down and choose "Calculate". The calculator will output the values of a (slope) and b (y-intercept) for the regression equation.
5. To view the equation, press the STAT button again and go to TESTS. Scroll down and select "5: Equation". The regression equation y = ax + b will be displayed on the screen.
Note: The equation will be displayed with the coefficients rounded to a certain number of decimal places. If you need more precise values, you can access the coefficients by pressing the VARS button and selecting "5:Statistics". Then choose "5: LinReg" to see the values of a and b.
Remember to refer to your calculator's manual for specific instructions, as the steps may vary slightly depending on the calculator model.
