### How to solve direct and inverse variation problems?

Solve direct &amp; inverse variation word problems. By Yay Math. 3/24/10 9:40 PM. WonderHowTo. In this video the instructor teaches about direct and inverse variation. Two variables x and y are said to be in direct variation with each other if you can write them in the form y = K * x. The value of y varies directly corresponding to the value of x.

### How do you use the formula for direct variation?

The keywords' meanings are: directly: things are working together; you are multiplying everything. inversely: things working against each other; you are dividing something somewhere. jointly: many things are working together; you are multiplying lots of stuff.

### What is the formula for indirect variation?

The cases you’ll study are: Direct Variation, where one variable is a constant multiple of another Inverse or Indirect Variation, where when one of the variables increases, the other one decreases (their product is constant) Joint Variation, where more than two variables are related directly More items...

## Direct and Indirect Variation - Montgomery County …

Direct and Indirect Variation. Indirect Variation. We gave an example of inverse proportion above, namely speed and time for a particular journey. In this case, if you double the speed, you halve the time. So the product, speed x time = constant. In general, if x and y are inversely proportional, then the product xy will be constant.
