Video on Direct Variation - Algebra Help

Students learn that if each y value in a function is the result of multiplying each x value by the same number, then the function is an example of direct variation. And the formula for direct variation is y = kx, where k represents the constant of variation.
Video on Direct Variation - Constant of Variation

Students learn that direct variation is a relationship between two variables in which the variables have a constant ratio, k, where k is not equal to zero. k is called the constant of variation, and if the variables are x and y, the following formulas can be used to represent direct variation: y/x = k or y = kx.

You will learn given the direct variation equation, to identify the constant of variation and the relationship between k and m.
