See explanation
Explanation:
Basically this means all those values of y that are less than 3.
If you wish to do a 2 dimensional representation of this (graph) you plot

Another way of showing this would be to use a number line. I am not sure about the convention regarding horizontal or vertical. I choose horizontal:
Notice the hollowed dot at the three. This signifies that the value may not be 3. You would use a solid dot if it could. I forgot to label the line. You would have to state is as being the value of y.
