Question

Suppose y varies directly as x. Write a direct variation equation that relates
x and y. Then solve.
If y = -8 when x = -2, find x when y = 32

how do i solve this?

Answer 1

help??

Answer 2

\[y=kx\]
\[-8=k(-2)\]
\[\frac{-8}{-2}=k\]
\[4=k\]
\[y=4x\]

Answer 3

i need to find x when y =32

Answer 4

yes, so now you need to solve
\[32=4x\] for \(x\)
can you do that?

Answer 5

do you just divivde by 4? so then x =8?

Answer 6

yes and yes

Answer 7

thank you!!!
