direct variation, and in the equation y=kx the k ca NOT equal 0.
To determine if a relationship represents direct or inverse variation, examine how the variables change in relation to each other. In direct variation, as one variable increases, the other also increases (e.g., ( y = kx ), where ( k ) is a constant). In inverse variation, as one variable increases, the other decreases (e.g., ( y = \frac{k}{x} )). You can also look for a constant ratio or product; in direct variation, the ratio ( \frac{y}{x} ) is constant, while in inverse variation, the product ( xy ) is constant.
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.
The slope of the graph of a direct variation is always positive.
Direct variation.
A variable, Y, is in direct square variation with a variable, X, if Y = kX2 where k is some (non-zero) constant.
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 .
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 .
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).

A variable y is said to be in direct variation with a variable x if there is a constant c (>0) such that y = c*x. c is called the constant of direct variation or proportionality.
