Question

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

Answer 1

Answer:

It does not show variation

Step-by-step 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
