Our inequation is
[tex]b<4[/tex]
It means we will graph every point that satisfies the inequation, we can read it as values at the axis that satisfies "b" less than 4. Some examples that satisfy it
3 is less than 4, then it must be in the graph
1 is less than 4, then it must be in the graph
-1 as well
-3 too, -6, -100, -2000 and so on.
But see it's only less than, equal to 4 is not included in the solution, we represent it as
It means that our graph will be like
We will put the empty circle at 4 and paint all on the left side.
