MA.7.AR.4.2 · Proportional Reasoning and Relationships
Students find the constant of proportionality from a table, a graph, or a written description. If a line passes through the origin and the point (5, 2), the constant is 2/5; if a babysitter earns $9 per hour, the constant is the 9 in the equation e = 9h.
On the FAST, students answer equation editor items entering the constant and multiple choice items reading it off a graph or a table. This benchmark is drawn twice per practice test. The most common error is inverting the ratio, so students have to track which quantity is y and which is x.
