y=3x is a direct variation in that y varies directly with x by a factor of 3. Any linear equation (a polynomial of degree 1, which is a polynomial equation with a highest exponent of 1), is a direct variation of y to x by some constant, and this constant is simply the coefficient of the "x" term. Other examples: y=(1/2)x is a direct variation, and the constant of variation is 1/2 y=-9x is a direct variation, and the constant of variation is -9
2y - 3x = 0Put into Slope-Intercept form:2y = 3xDivide by 2:y = 3/2 * x = 1.5x3/2, or 1.5 is the constant of variation.
3x + 2 = 3x + 6 This is not possible.

Yes, it is direct variation.

find the direct variation equation 3x+y=0
no
The question is not clear. But if you want this in the form y=kx, then k must be 1.5
2y - 3x = 0Put into Slope-Intercept form:2y = 3xDivide by 2:y = 3/2 * x = 1.5x3/2, or 1.5 is the constant of variation.
3x + 2 = 3x + 6 This is not possible.
3x plus 9 equals what?

Their graphs are.
