SAT Mathematics Practice Test 6

Choice B is correct. Both sides of the given inequality can be divided by 3 to yield $2\mathit{x}-3\mathit{y}>4.$
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 $\left(0,-1.5\right)$ is a solution to the given inequality, but it is not a solution to any of the inequalities in choices A,C or D.
