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.
What else can I help you with?
Is y equals 2x plus 5 a direct variation if so what is the constant of variation?
No, it is not a direct variation.
2X plus 2X plus 9X equals?
it equals 13X.
Is y-2x direct variation?
No, the expression ( y - 2x ) does not represent direct variation. In a direct variation, the relationship between two variables can be expressed in the form ( y = kx ), where ( k ) is a constant. The equation ( y - 2x = 0 ) can be rearranged to ( y = 2x ), which does show direct variation, but the original expression itself does not imply this relationship without further context.
