Explanation
Choice B is correct. Both sides of the given inequality can be divided by 3 to yield 
.
Choices A, C, and D are incorrect because they are not equivalent to (do not have the same solution set as) the given inequality. For example, the ordered pair 
is a solution to the given inequality, but it is not a solution to any of the inequalities in choices A, C, or D.
