   What is direct variation and inverse variation?

   • Direct variation and inverse variation are used often in science when modelling activity, such as speed or velocity. This video explains direct variation and solves application problems. This video provides and example of how to determine a direct variation equation from given information and then determine y with a given value of x.

   What is joint variation?

   • Joint variation is just like direct variation, but involves more than one other variable. All the variables are directly proportional, taken one at a time. Let’s set this up like we did with direct variation, find the k, and then solve for y; we need to use the Formula Method:

   What is an example of direct variation?

   • The cases you’ll study are: Direct Variation, where one variable is a constant multiple of another. For example, the number of dollars I make varies directly (or varies proportionally) to the number of hours I work. Or, the perimeter of a square varies directly with the length of a side of the square.

   What is inverse variation?

   • Inverse variation is a relation in which the absolute value of one variable gets smaller while the other gets larger. Inverse variation and direct variation are important concepts to understand when learning equations and interpreting graphs. This video explains and provides examples of inverse variation.

   What are the different types of variation?

   • We will learn about what is variation, direct variation, indirect variation and joint variation. In Mathematics, we usually deal with two types of quantities-Variable quantities (or variables) and Constant quantities (or constants). If the value of a quantity remains unaltered under different situations, it is called a constant.

   A variation is a relation between a set of values of one variable and a set of values of other variables. Direct variation. In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation.
