Question 514310: Take a look at the following table:
X -2,-1,0,1,2
f(x)-5,-2,1,4,7
a. Write out an equation for f(x). Assume the function is linear.
b. 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
---
slope: Notice that when x increases by 1, y increases by 3
intercept: Notice that when x is 0, y = 1
---------------------------------------------------
a. Write out an equation for f(x). Assume the function is linear.
f(x) = 3x+1
----------------
b. What is the slope?:: 3
-----
Is it negative or positive?:: positive
-----
What information do we get from the slope?
As x increases by 1, y increases by 3
