Question

Given that y varies directly with x, and x = 24, y = 3, how do you write a direct variation equation that relates x and y?

Answer 1

`y=1/8x`

Explanation:

By the problem
`y prop x`
`=>y=k*x` ,where k is variation constant.
No it is given `y=3 ,"when" x=24`
So `3=k*24`
`:.k=3/24=1/8`
Hence the variation equation becomes `y=1/8x`
