How do you graph this function f(x)=-2x+9
---
You only need 2 points to graph a line.
If x = 0, you get y = 9, so you have point (0,9)
--------------
If x = 2, you get y = -4+9 = 5, so you have point (2,5)
----------------------------------

How do you determine what to put in your table to plot points.
You may choose any values you want for "x". "y" will be
determined by using the equation.
