Well in the coordante :  (2,4) whats the x value and whats to y value?

anonymous · Answer

The 2 is the x and the 4 is the y if thats what your asking.

anonymous · Answer

ok, good, so now, or each relation which one has diffrent y values
E.g.
For this relation 
{(1, 2), (0, 3), (1, 3), (0, 2)} 
This has SAME y values becuase of 2 
so now find a relation with DIFFRENT y values
