If the ordered pairs below vary directly, find the missing value

1. (2,-6) and (5,y)

2,-6

5,y

so we add 3 to the 2 to make it to a 5

so i think we add the 3 to the -6 to make it to a -3

so i think the answer is -3

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
