Question

Determine the constant of variation for the direct variation given.

(0, 0), (3, 12), (9, 36)
O12
04
03

Answer 1

answer: 4

explanation: the rule is 4x = y

if you plug in the x-value 0 for 4(x)=y, then you would get the y-value 0
which makes it (0,0)

and then plug in the other x values 3 and 9:

4(3) = 12
(3, 12)

4(9) = 36
(9, 36)
