Question 4780
I think you are talking about an inequality in a form such as
y< mx +b, y> mx + b, ax +by < c, ax + by > c, or perhaps using symbols for "less than or equal to" or "greater than or equal to".


For inequalities in which y < mx + b or ax + by < c, the area below the line will be shaded, provided the y-coefficient is POSITIVE.


Likewise, for inequalities in which y > mx + b or ax + by > c, the area above the graph will be shaded, again provided the y-coefficient is POSITIVE.  


The same rule applies for symbols for "less than or equal to" and "greater than or equal to".  This may need further explanation or examples.  I hope I am answering the right question.
