Answer:
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 : [tex]y=kx\\ y=mx +b\\[/tex]
⇒b=0 , m=k
So it is of direct variation if it passes through the origin (0,0)
