Math Grade 7 Quiz Identifying the Constant of Proportionality – 7.RP.A.2.B
This standard focuses on identifying the constant of proportionality, also known as the unit rate, in various representations of proportional relationships. The constant of proportionality is the value that relates the two amounts that are always in the same ratio. Students learn to recognize this constant in tables, graphs, equations, diagrams, and verbal descriptions, an essential skill for understanding direct proportionality and how different variables change in relation to each other.
