Question

Direct variation or not a direct variation

y=5/x

Answer 1

not direct variation

Explanation:

The equation for x and y in direct variation is

y = kx ← k is the constant of variation

y =
`(5)/(x)` is not in this form, thus not direct variation.

The equation for x and y varying inversely is

y =
`(k)/(x)` ← k is the constant of variation

y =
`(5)/(x)` is in this form and represents inverse variation
