Question

Find the variation constant and an equation of variation where y varies directly as x and y=32 when x=8
The variation constant is k=
The equation of variations is y=

Answer 1

I'm not really sure what you want here. But if i understand correctly, it will be y=4x.

thus, when x = 8, it will be y = 4*8 = 32

is that what you want?

Answer 2

Honestly I'm not really sure either :(, sounds good though thank you!!

Answer 3

What would the k =?

Answer 4

y = kx

32=k(8)

32/8 = k

k = 4

So the equation is y = 4x

Answer 5

ok so k=4 and y=kx?

Answer 6

k=4 and y=4x

Answer 7

You replace k with 4

Answer 8

OH ok, I get it now, sorry. Thanks for all your help!! :)
