d.y=3x-3
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
In direct variation, one variable is the other multiplied times a number,
so when x=0, y=0
That is only true for answer

If youu graph a direct variation function,
it is a straight line that goes through point (0,0), the origin.
Direct variation is a special kind of linear relationship.

The other answers show a linear relationship
that is not a direct variation,
and if you graphed those functions,
you would get straight lines that do not go through the origin.
