Question 1066157
In direct variation, one variable is the other multiplied times a number,
so when x=0, y=0
That is only true for answer
{{{highlight(C)}}}{{{highlight(3x=6y)}}}
 
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.
