Question

It is given that yvaries directly as x. If y= 5 when x= 4 determine the constant of variation,

Answer 1

`k=(5)/(4)`

Explanation:

Given that,

y varies directly as x. It means,

y = kx

Where

k is the constant of variation

or

`k=(y)/(x)\\\\k=(5)/(4)`

So, the constant of variation is
`(5)/(4)`.
