Question 453096
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)
----------------------------------
Graph:
{{{graph(400,300,-10,10,-10,10,-2x+9)}}}
------------------------------------ 
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.
---------------------------

Does it matter if the line is going in opposite direction.
Yes
