Answer:

Any graph which passes through the origin(0,0)

Explanation:

To check a graph if it represents direct variation or not, one needs to check whether it passes through the origin or not .

So any graph which passes through the origin is of direct variation.

And in equation form :
$y=kx\\ y=mx +b\\$

⇒b=0 , m=k

So it is of direct variation if it passes through the origin (0,0)
