Learning Target:
- I understand what a specific point on a graph means in the context of a problem.
- I can analyze a graph to determine if a relationship is proportional.
CCSS:
- 7.RP.2 Recognize and represent proportional relationships between quantities.
- a. 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.
- 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.
