So, when you test cases, it has to be a little more interesting. Basically, in statement 1 you have to pick a value of y that's greater than 1/|x| (or less than -1/|x|), and vice versa for statement 2.
E.g., in statement 1, if x = 1/3, then you have to pick y > 3 or < -3.
(If you don't see why, try it! You'll notice what happens if x = 1/3 and y = 3. From there, you can discern pretty quickly why y has to be bigger.)
Also, with the two statements together, if you don't IMMEDIATELY see the number properties at work, just start testing values.
Once you try a couple of values that fit both statements together, it will become abundantly clear what is going on, even if you didn't think about "fraction properties" to begin with.
