Systems of Inequalities
(page 2 of 4)
---- This algebra lesson explains how to solve
systems of inequalities (linear programming). |

|
Let's try another one:
| Remember how to graph |
 |
? Think
y =
mx
+ b! |
 |
The line is dashed since there is
no " = " in the
 .
What side do we shade?
Pick a point NOT on the line
and try it! |
Let's try
(1,
0)
...
|
Nope! This doesn't work!
So, shade the other side. |
 |
Remember that this means that ALL
the points in the shaded area work in our inequality.
TRY IT:
| Graph |
 |
( Be careful!
Get it in y = mx + b form! )
