Question 276492: take a look at the following table.
x -2 -1 0 1 2
f(x) -5 -2 1 4 7
Write out an equation for f(x). assume the function is linear. What is the slope? Is it negative or positive? What information do we get from the slope?

x -2 -1 0 1 2
f(x) -5 -2 1 4 7
Write out an equation for f(x)
assume the function is linear.
f(x) = 3x + 1
--------------
What is the slope?
m = 3 (slope)
---------------
Is it negative or positive? = +3
------------------
What information do we get from the slope?
It's the change in f(x)/change in x
