-2 > 0

False

The inequality x - y > 0 is satisfied by point (-1, 1).

False

i think the correct option is the second option.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
