How would I tell which of the options it is?

sweetburger · Answer

plug in the point (0,0) into each equation

sweetburger · Answer

dont get much easier than that

random231 · Answer

http://prntscr.com/3quvmo plug in (1,2) most of the equations satisfy (0,0)

lncognlto · Answer

But surely  (0,0) satisfies a few equations..

sweetburger · Answer

well it does but then you go ahead and plug the ones that do in the graphing calculator or go and pick another point

anonymous · Answer

Well it can't be B or D because then it couldn't have the coordinate (0,0). I wouldn't just plug in (0,0) to any equation because it could be multiple. It can't be A because (1,2) doesn't fit in the equation. It can't be C because it doesn't fit (2,6). E fits everything, so go with that.

random231 · Answer

its B

anonymous · Answer

Using B has the coordinate (0,-1), which isn't on the graph, so it's not B.

lncognlto · Answer

Ohh, okay, I see. The correct answer is satisfied by both (0,0) and (1,2). I got it. Thanks!
