No, it is not a direct variation.

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

y equals 4x+1 is a parallel line to y equals 4x.

y = kx: 10 = 37k so k = 10/37 and y = 10x/37

4x = y : or it can be written in the reverse order, y = 4x.
