Which set of ordered pairs is a linear function? A {(3, 1), (2, 0), (-1, 1)} B {(4, 4), (0, -6), (2, -1)} C {(-1, 2), (3, -4), (12, 5)} D {(0, 0), (1, 1), (2, 5)}
You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function.
