Question 93860
graph this inequality. 
y >= 3x 
----------------
It sounds like you have graphed the line y = 3x.
That is part of the solution and it is the boundary 
of the inequality.
----------------------
To determine where the graph of the inequality is you
should select a test point that is not on the line,
like (1,1)
---------------
Test the x and y values of the test point in the inequality as follows:
1 > 3*1
That is false.
So shade the half-plane that does NOT contain (1,1).
---------------
Comment: That half-plane should be above the line y=3x.
