Determining the Constant of Proportionality from a Graph

The video tutorial explains how to determine the constant of proportionality in graphs by finding the ratio of y to x. It begins with an introduction to graphing and the coordinate plane, detailing the quadrants and how to identify proportional relationships. The tutorial then focuses on calculating the constant of proportionality, using examples to illustrate the process. Finally, it applies the concept to real-world scenarios, such as finding the unit rate of miles per hour, and writing equations to represent proportional relationships.
