Constant of Proportionality

The video tutorial explains how to identify the constant of proportionality in proportional relationships using graphs and tables. It introduces the concept of the constant of proportionality, represented by 'k', as the ratio of y to x. The tutorial provides examples using both table and graph data to calculate 'k', demonstrating that it remains constant across all related x and y pairs. The video concludes by summarizing the process of identifying the constant of proportionality.
