Here's another one:

Graph  2x + y > 4
First, do the line:

the graph of the line 2x + y > 4 ... remember the line is dashed

We make it a dashed line since there is no =.

So, which side do we shade?

Let's try ( 0 , 0 ):

2x + y > 4 ... 2 ( 0 ) + 0 > 4 ... 0 > 4 ... Nope!

( 0 , 0 ) doesn't work!  That means nothing on that side will work ... So, all the good points must be on the other side!

the graph of 2x + y > 4 ... the portion of the graph above the line is shaded All the points in the shaded region work in

2x + y > 4


TRY IT:

Graph x + y > -2
