Answer:
C
Explanation:
Let's see if this makes sense and applies to all of the pairs.
1. y will be 2
x will be 6
2=1/3(6)
1/3 times 6 is 2.
2. y will be 1
x will be 3
1=1/3(3)
1/3 times 3 is 1.
3. y will be 0
x will be 0
0=1/3(0)
1/3 times 0 is 0.
4. y will be -1
x will be -3
-1=1/3(-3)
1/3 times -3 is -1.
They all apply to C meaning that C is the right answer.
