Direct variation refers to two variable quantities have a constant (unchanged) ratio, in which a variable "varies directly with the other."
In order to have a direct variation, the constant of variation must be not equal to 0 in the equation y=kx, where k is the constant.
When you try to put 2x+3y=0 into that formula (y= form), you get:
2x+3y=0
3y=-2x ;Subtract the 2x
y=(-2/3)x ;Divide by 3
Your constant of variation is -2/3, and since it is less than 0, it is does variate directly. Therefore, y varies directly as x.

How do you know if the equation is a direct variation?
When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation. y=2x is direct variation y=x+2 is not direct variation
