1.3a Is the Graph Proportional? Constant of Proportionality

Learning Target:

I can determine the constant of proportionality for a problem.

CCSS:

7.RP.2 Recognize and represent proportional relationships between quantities.
- b. Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
- d. Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate.
