Question

What is the constant of variation for the following direct variation?

PLEASE HELP IVE CRIED OVER THIS 6 TIMES ALREADY

Answer 1

I think it’s B sorry if I’m wrong

Answer 2

B

Explanation:

the equation of direct variation is

y = kx ← k is the constant of variation

divide both sides by x

`(y)/(x)` = k

substitute either of the ordered pairs from the table into the equation

using (4, 2 ) , then

k =
`(2)/(4)` =
`(1)/(2)`

using (12, 6 ) , then

k =
`(6)/(12)` =
`(1)/(2)`

the constant of variation is k =
`(1)/(2)`
