Question

Write the direct variation equation for the following: y varies directly with x and y = 60 when x = 10.
y = 1/6 x
y = -1/6 x
y = 6x
y = -6x

is it the first one?

Answer 1

uuuuuuh?

Answer 2

so the answer is c...

Answer 3

oooooooh

Answer 4

the equation for "y varies directly with x" is y = kx

Answer 5

wait why c?

Answer 6

and because y = 60 when x = 10, 60 = 10k

Answer 7

ok got it

Answer 8

when we divide both sides by 10, we get k = 6

Answer 9

so our answer is y = 6x

Answer 10

thanks

Answer 11

no problem :)
