Question

Determine the constant of variation for the direct variation given.
(0, 0), (3, 12), (9, 36)
3
4
12

Answer 1

3

Answer 2

Direct variation has the form: \(y = kx\)
So, \(k = y/x\) for \(x \ne 0\)
Try dividing the y by the x in the nonzero points

Answer 3

and no, its not 3. 12/3 = 4
36/9 = 4

Answer 4

SO THEN.. which one is it?
