Press the down arrow to select the plot type.

Press the 2nd button followed by the Y= key to get STAT PLOT.

Replace L1 and L2 below if you are storing your data in other locations. This is assuming that the x coordinates are in L1 and the y coordinates are in L2. To plot the data points, follow the steps below. You can plot the regression line in Y3 in the same way that you plot any function.

Press ENTER to calculate the regression line and store the result in Y3.

Press the right arrow to get to the Y-VARS menu.

Press the 2nd button followed by the 2 button to get L2.

Press the 2nd button followed by the 1 button to get L1.

Press 4 to select the LinReg (ax + b) function.

Press the right arrow key to move over to the CALC menu.

Press the STAT button to get to the statistics window.

Replace L1, L2, and Y3 below if you are storing your data in other locations. These are the steps for calculating the regression line if the x coordinates of the points are in L1, the y coordinates of the points are in L2, and you want to store the equation in Y3. You can use the arrow keys to go back and correct mistakes.

Enter the x values into L1 by typing the first number, pressing ENTER, typing the second number, pressing ENTER, etc.

This will allow you to enter lists of numbers, names L1, L2, etc.

Press the STAT button to get the statistics window.

Calculation of the regression line requires three steps: entering the data points, calculating the regression line, and plotting the data points and the line. Linear regression is a statistical method for finding a line that is as close as possible to a set of data points.
