The constant of variation in an http://wiki.answers.com/Q/inverse-variation.html is the constant (unchanged) product between two variable quantities.The formula for indirect variation is xy = k..where k is the constant of variation.The constant of variation in a http://wiki.answers.com/Q/direct-variation.html is the constant (unchanged) ratio of two http://wiki.answers.com/Q/variables.html quantities. The formula for direct variation is y = kx..where k is the constant of variation.

what is the constant variation of k if x=.5 and y=1

yes y=kx is the formula for direct variation, and k represents constant of variation which can also be called slope.

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

No, it is not a direct variation.

Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .
