I need help answering this question
Which one of these answers are correct?
 3x - 2y greater than or equal to 4
		
3x - 2y less than or greater to 4
		
3x - 4y less than or greater to 2
		
The correct inequality is not listed.

ok look at it this way.   if the line is solid it is equal to because the line is the solution
if the line is dotted, you will only have less than       or you will have greater than
it can not say both, and the line is not the solution.
the shaded side contains all possible solutions so take a point from the shaded side and sub (x,y) and see if it is true
