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 variation between two variable quantities with a constant ratio is called direct variation. In this relationship, as one variable increases or decreases, the other variable changes in proportion, maintaining the same ratio. Mathematically, this can be expressed as ( y = kx ), where ( k ) is a constant.

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.

Direct variation.
Direct variation occurs when two variables change in the same direction; as one increases, the other also increases, typically expressed as ( y = kx ), where ( k ) is a constant. Indirect variation, or inverse variation, happens when one variable increases while the other decreases, represented as ( y = \frac{k}{x} ). In direct variation, the ratio of the two variables remains constant, while in indirect variation, the product of the two variables remains constant.
