Being a second year calculus student at University, inequalities are nothing more than a facet of everyday life. I was helping my grade 9 brother out with some inequality theory he didn't understand, easy peasy, until I saw this piece of shit.
The question is "Determine which inequality matches the number line".
I'm temped to just write down x=-2, x=-1, x=0, x=1, x=2, but I'm not sure if this is correct.
In Canada, lessthan/equalto and greaterthan/equalto are defined as solid circles, and greaterthan/lessthan are open circles.
Any thoughts?

-2<x<2, x∈integers?

-2 <= x <= 2? Seems easier :)
