Which graph represents a direct variation between the quantities x and y

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

Step-by-step 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 :

                                      ⇒b=0 , m=k

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