Ordered pairs that have a negative x and a positive y are in the second quadrant.
The domain is all the first coordinates in a relation. A relation is two ordered pairs.
In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
Y is the second number in a set of ordered pairs.
Describe how to find the domain and range of a relation given by a set of ordered pairs.
