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 x varies directly as y, then

x= ky, where k is any constant

If x varies inversely as y, then

x = k/y, where k is any constant

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 .

It is called direct variation.

if the line runs through the origin it is a direct variation no matter if it is increasing or decreasing

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).

direct means it stays the same while inverse means it will change.

No, this is an inverse variation.

Inverse variation does not pass through the origin, however direct variation always passes through the origin.

Direct

Suppose the two variables are denoted by X and Y. If Y is a constant multiple of X, that is Y = c*X, then the variation is direct. If the value of X*Y is a constant, that is Y = c/X, then the variation in inverse.

direct varation is when both x and y rise and decrease by the same number. inverse is when x or y decreases, the other one increases by the same number

No. This is not true. It is false. The equation is an example of direct variation.

the relationship between pressure and volume a direct or inverse?
