First, let's do a
quick review of graphing line inequalities:
Let's graph
Graphing the line, itself, should
be a no-brainer for you... But, figuring out which side should
be shaded is often the snag.
Here's the line:
 |
The line is solid because of the
" =
" in the
...So... what side
gets shaded?
To figure this out, we just
pick a point that is NOT on the line and see if it works in
 |
Let's try
(0,
0)
since it's so easy to work with:
 |
If
(0,
0) works, then
everything on his side of the line will work --
So, shade that side! If it didn't work, then we'd shade
the other. |
