Question

How do you determine the constant of variation for the direct variation given `Y=-3/2x`?

Answer 1

`k=-3/2`

Explanation:

The statement "y varies directly as x" can be algebraically expressed

as: `y=kx` , where `k` is the constant of variation, so in this case:

`y=-3/2x` , the constant of variation is:

`k=-3/2`
