Students explore the relationship between proportional and non-proportional relationships/direct variation.
Students learn what the constant of proportionality is, and how to identify it in a graph, table, and equation
Students will explore real-life situations that are proportional, and situations that are not proportional, and draw conclusions.
Students will discover:
-Proportional tables have a constant ratio, change at a constant rate, and x and y will both equal zero at the same time.
-Proportional graphs are linear, and pass through the origin.
-Proportional equations are in the form y=kx, where k represents the constant of proportionality.
