from the main menu and
GCD
from the sub-menu.

3. Enter
4656,
764,
8794
between the parentheses and press

1. Press
D
(and tap

2. Select
Function
from the main menu and
SLOPE
from the sub-menu.
The function
SLOPE()
appears on the entry line ready for you to specify the function and the
x
-
value (separated by a comma). Note that if the current app is not the Function app, what appears on the entry line is
Function.SLOPE()
.
3. Enter
2*X
2
–9*X,2
and press
E
.
The result is –1.
