Parallelogram \$ABCD\$ has vertices \$A(3,3)\$, \$B(-3,-3)\$, \$C(-9,-3)\$, and \$D(-3,3)\$. If a point is selected at random from the region determined by the parallelogram, what is the probability that the point is not above the \$x\$-axis? Express your answer as a common fraction.

Must the point have integer coordinates?

If so, list all the possible points, count how many are not above the x-axis and count the total number of points, and divide the answers.

If not, there are an infinite number of points possible. The number of points on the x-axis can be can be added to those below the x-axis without increasing the (infinite) number. Then, there will be as many points below the x-axis as above the x-axis, so the answer will be 1/2.
