Algebra 2 - Determining direct variation from a table

The video tutorial explains how to determine if a function is an example of direct variation. It introduces the concept of direct variation, represented by the equation Y = KX, where K is the constant. The tutorial provides a step-by-step example using a table of values to check if the K value remains consistent across different pairs of X and Y. If the K value is the same, it confirms direct variation. The example concludes with rewriting the equation using the determined K value.

Given the values 9/27, 10/30, and 20/60, what can you conclude about their relationship?
