Proportional Relationships Webquest


We know that a proportion occurs when two ratios/fractions are equal or have the same value. In this lesson you are going to determine whether a table and graph is proportional, by finding the constant of proportion.


SWBAT calculate k, the constant of proportionality given a table of values and a  graph.

Now click the task tab.

Youtube video-Identifying the constant of Proportion:


Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.

Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.
