First step is to find the "equals" part. For two-variable linear inequalities, the "equals" part is the graph of the straight line. In this case, that means the "equals" part is the line 2x-3y = 3.

Let's change the equation a bit so it's easier to graph shall we?
2x - 3y = 3
-3y = 3 - 2x
y = (3/-3) - 2x/-3
y = (2/3)x - 1

Graphed, the "equals" part looks like
|dw:1334700369318:dw|

Now for the less than. What we want to show is that every y beneath that line is also a valid answer. To do that, we color it in!
So the less than or equals looks kind of like:
|dw:1334700631889:dw|
