Question

Tell whether x and y show direct variation. Explain your reasoning. y−x=0

Answer 1

yes

Explanation:

Direct variation is represented as

y = kx, where k is a constant.

We can rewrite y - x = 0 as

y = x (add x to both sides)

This can be looked at as

y = (1)x , so this is a direct variation relationship where k = 1
