Direct variation.
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.
It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.
A direct variation is a situation in which two quantities -- such as hours and pay, or distance and time -- increase or decrease at the same rate. The ratio between the quantities is constant; that is, as one quantity doubles, the other quantity also doubles. so yes it is. -add on- A direct variation is in the form y=ax where a is an constant.
Well, they're both variables.
