- From the initial Stat screen, press

(A+BX) for linear regression.**2**

- Enter the x-values into the table by pressing

- Use the arrow keys to move to the top of the y-column and enter the y-values by pressing

## STAT MODE

**Finding a Regression:**

- To find the regression equation, press to clear the screen.

- Press(STAT) to display the Statistics Menu.

- Press

(Reg) to find the coefficients for the linear regression equation.**5**

- Press
(A) to find the value of`1`

**A**.

- To find the value of B, repeat the process. Press

- The values of the correlation coefficient (
**r**), the estimated value of X, and the estimated value of Y can also be found.

## TABLE MODE

TABLE generates a number table based on one or two functions, entered as f(x) and/or g(x). Press to enter TABLE mode.

**Note:** Be sure to input the x variable when generating a number table. All other variables will be handled as constants.

- Enter the function (f)x = 2x + 1 by pressing

- Press to store that function. Another function can be entered to compare the two functions. Pressto moves to the next screen and only has one function entered.

- Set a starting x-value for the table. The default value is 1. To change the value, enter the new value and press. To keep the existing value, press.

- Next, set an ending x-value for the table. The default value is 5. To change the value, enter the new value and press. To keep the existing value, press.

- Set a step value for the table. The default value is 1. To change the value, enter the new value and press. To keep the existing value, press.
