Take a look at the following table:
x -2 -1 0 1 2
f(x)-5 -2 1 4 7
-----------------------
Note: As x increases 1, f(x) increases 3; so the slope is 3
Note: When x is zero, f(x) is -2 ; so the intercept is -2
---------------------------------------------------
a. Write out an equation for f(x). Assume the function is linear
f(x) = 3x-2
----------------------------
b. What is the slope? Is it negative or positive? What information do we get from the slope?
Slope = 3 ; positive ; as x increases 1, f(x) increases 3.
