Have you considered translating the text into notational equivalents?

"Three less than two-third of x is greater than or equal to y"

two-third of x ==> $\dfrac{2}{3}x$

Three less than two-third of x ==> $\dfrac{2}{3}x - 3$

Three less than two-third of x is greater than or equal to ==> $\dfrac{2}{3}x - 3 \ge$

"Three less than two-third of x is greater than or equal to y ==> $\dfrac{2}{3}x - 3 \ge y$

You do the other one.

@celinegirl:   I have a problem with your asking one of your helpers "are you sure?" in regard to the correctness of his help to you.  First of all, it's important that YOU learn how to check your own answers.  Secondly, you haven't shown your helpers any work at all.  Third, that "are you sure?" question could be construed to be insulting to someone who is helping you as a volunteer.

Next time, consider doing the graphing yourself and then comparing your graph to the four possible answer graphs.  You'd learn more from doing that than from asking someone else to check your work.

@mathmale um? 1. I was thinking the answer was B for the longest time now and when a helper comes and says they THINK a different answer, me asking "are you sure?" it me asking for them to explain to me more easily how they got that answer. DO NOT make accusations that you do not understand!!!

@celinegirl:  I'm sorry you don't care for what I said earlier, but on the other hand I'm sticking with all of it.  I'd be happy to help you, as would others, if you'd please do and share some work of your own.  With an accurate graph of your own to compare to the four given graphs, you should have little or no problem selecting the correct answer.
