A direct variation function contains the points (-9, -3) and (-12, -4). Which equation represents the function?

1. y = -3x
2. y = -x/3
3. y = x/3
4. y = 3x​

Answer 1

Answer: y = x/3

Explanation:

(-9,-3)(-12,-4) written in y = mx + b form is y = 1/3x, and I'm pretty sure that means the answer is 3. y = x/3
