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
Speed and distance: the faster you go, the further you can go in a fixed amount of time.
A direct variation (!) or direct reelationship.
No, it is not a direct variation.
I have recently been doing all these direct variation problems but not every linear relationship is a direct variation... But every direct variation is a linear relation!

A variable, Y, is in direct square variation with a variable, X, if Y = kX2 where k is some (non-zero) constant.

what are examples of bacterial variation?
Direct variation is not a special case.
Yes, it is direct variation.

If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
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 .
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. y=kx (or y=kx ) where k is the constant of variation .
