Students look at the relationship between the number of flags manufactured and the stars on the flag and determine whether it represents a proportional relationship.

Key Concepts

The form of the equation of a proportional relation is y = kx, where k is the constant of proportionality.

A graph of a proportional relationship is a straight line that passes through the origin.

The constant of a proportionality in a graph of a proportional relationship is the constant ratio of y to x (the slope of the line).

Goals and Learning Objectives

Identify the constant of proportionality in a proportional relationship based on a real-world problem situation.

Write a formula using the constant of proportionality.

Analyze a graph of a proportional relationship.

Make a graph and determine if it represents a proportional relationship.

Identify the constant of proportionality in a graph of a proportional relationship.
