Yes, it is direct variation.
The question is not clear. But if you want this in the form y=kx, then k must be 1.5
3x - y = 4 Get y by itself to see if it is the same as y = 3x - 4: 3x = 4 + y 3x - 4 = y Therefore, 3x - y = 4 is the equivalent of y = 3x - 4.
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2

y = 2 sin 3x y' = 2(sin 3x)'(3x)' y' = 2(cos 3x)(3) y' = 6 cos 3x
Yes
-2
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
find the direct variation equation 3x+y=0
No, it is not a direct variation.
The question is not clear. But if you want this in the form y=kx, then k must be 1.5
No.
y=7x
1
No, this is an inverse variation.
Direct
No.
