A student is testing points for the inequality $\frac{x}{3} - \frac{y}{2} > 1$. Which of their tests shows the correct work and conclusion?

Test point $(3, 2)$: $\frac{3}{3} - \frac{2}{2} = 1 - 1 = 0$. $0 > 1$ is false. So $(3,2)$ is not a solution.

Test point $(0, -2)$: $\frac{0}{3} - \frac{-2}{2} = 0 - (-1) = 1$. $1 > 1$ is false. So $(0,-2)$ is a solution.

Test point $(6, 0)$: $\frac{6}{3} - \frac{0}{2} = 2 - 0 = 2$. $2 > 1$ is true. So $(6,0)$ is not a solution.

Test point $(-3, -4)$: $\frac{-3}{3} - \frac{-4}{2} = -1 - (-2) = 1$. $1 > 1$ is false. So $(-3,-4)$ is a solution.

Test point $(9, 4)$: $\frac{9}{3} - \frac{4}{2} = 3 - 2 = 1$. The point is on the boundary line, so it is a solution.
