Description Identifying Proportional Relationships in Tables
After this lesson you will be able to identify proportional relationships in tables.
The lesson begins with a table representing two quantities. It leads to recalling the definition of a proportional relationship. It concludes with determining whether a table represents a proportional relationship by simplifying ratios.

This video includes key concepts, notation, and vocabulary such as: proportional relationships (a constant ratio, or the unit rate); ratio (a comparative, proportional relationship between two amounts); and ratio tables (a table of equivalent ratios).
Before watching this video, you should already be familiar with the definition of a proportional relationship and the equation y=kx.
After watching this video, you will be prepared to learn whether two quantities are proportional to each other by graphing on a coordinate plane.

Hi Danna Rouse, We apologize for this mistake and understand that this is confusing for your students, thank you for letting us know! Have you already seen this video?https://us.sofatutor.com/mathematics/videos/proportional-relationships-and-measuring-rates?topic=3182 It might be more understandable for your students.
We hope we could help you,
Best wishes from the content team.
The constant of proportionality is y=kx; therefore the relationship of the independent variable and dependent variable is always k=y/x, not the other way around. The content is cute but the error is substantial mathematically and very confusing for students who are just being introduced to linear equations. I could not use this material in my classroom.
