Four Representations of Constant of Proportionality
Overview
Four Representations of Constant of Proportionality help students use their knowledge of proportional relationships. Students identify the constant of proportionality from a word problem, an equation, a table, or a graph; and then use that knowledge to complete the other tasks.
