I need to figure out the slope and an equation for the following points.
(1,4), (2,16), (3,64), (4,256), (5,1024), (6,4096).
-----------------
there is no consistent slope; the points are not on a line.
----------------------
The equation for these points is an exponential equation:
y = ab^x
---
Substitute a couple of points into the form:
16 = ab^2
4 = ab
-----------------
Divide the 2nd into the 1st to get rid of the "a" factor:
4 = b
--------------
Substitute that back into one of the equations to solve for "a".
4 = a*4
a = 1
---------------
Equation:
y = 4^x (this is the equation the points fit into)
--------------
Here is the graph; you can see the slope is constantly changing.
