Show Work, Proportional relationships can be represented in different ways: tables, graphs, equations, and verbally. Three situations are described below. Match up the representations that have the same proportional reasoning as the scenarios described below. All scenarios will have at least one representation (items A-G) from the Table of Different Representations below.
Scenario 1: Mrs. Perez types 104 words in 8 minutes.
Representations with same proportional reasoning:
Scenario 2: y = 3.5x
Representations with same proportional reasoning:
Scenario 3:
Representations with same proportional reasoning:
Table of Different Representations
Match up the representations that have the same proportional reasoning as the scenarios described above. All scenarios (above) will have at least one representation (items A-G) from this table. Every representation below can be matched with a scenario above. You must match up them all to the correct scenario to get full credit for this problem.
