What is the formula for direct variation?

2y=3x


How do you find direct variation?

use the formula y=kx


Is the constant of variation the same as slope?

yes y=kx is the formula for direct variation, and k represents constant of variation which can also be called slope.


When two quantities form a direct variation what is it called?

A direct variation (!) or direct reelationship.


Is direct variation a special case?

Direct variation is not a special case.


Is y equals 3x direct variation?

Yes, it is direct variation.


What is indirect 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.


How does the constant of variation affects the appearance of the graph of a direct variation function?

The formula direct variation is xk=y, where k is the constant of variation.Direct variation functions always pass through the origin. Direct variation functions are linear functions (goes in a straight line), except that they pass through the origin. Regular linear functions don't pass through the origin. That is the only difference.


Is y equals 2x plus 5 a direct variation if so what is the constant of variation?

No, it is not a direct variation.


Does every linear equasion represent a direct variation relationship?

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!


How do you do a direct variation with an inverse variation problem?

If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).


What is the difference direct variation and inverse 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 .
