Question

Tell whether x and y show direct variation. Explain your reasoning. x=y+2

Answer 1

It does not show variation

Explanation:

Given

`x = y + 2`

Required

Determine if there's direct variation between x and y

The general form of direct variation is:

`y = kx`

Make y the subject of formula in the given parameters;

`x = y + 2`

`y = x - 2`

Compare
`y = x - 2` to
`y = kx`

Since they are not of the same form, then the given equation do not show direct variation
