If x > 4 and y < -4, then which of the following must be true ? Choose the correct answer.
A) x/y > 1  B) x/y < -1  C) x/y < 0  D) x + y > 0  E) xy > 0
Pick x=3, y = -3   A) x/y &gt; 1 - Incorrect as x/y = -1   B) x/y &lt; -1 - Incorrect as x/y = -1   C) x/y &lt; 0 -Correct. It will hold for all values x &gt; 2 and y &lt; -2 as x/y = -1 &lt; 0   D) x + y &gt; 0 - Incorrect. x + y = 0   E) xy &gt; 0 - Incorrect. XY = -9 which is less than zero.   xy &gt; 0 should be the answer.
