Answer:
(6, 1)
(1, 3)
(-7, 6)
Step-by-step explanation:
To have a function, each value used for x can appear only once.
The first set of points has as x: 1, -7, -3.
The only choice without 1, -7, or -3 for x is (6, 1)
The second set of points has as x: 2, 6, -7.
The only choice without 2, 6, or -7 for x is (1, 3)
The third set of points has as x: 1, -3, 6.
The only choice without 1, -3, or 6 for x is (-7, 6)
