Type of items: Type 1
Color Code: Peach
Evidence Statement Key: 7.RP.2c
Calculator: No
Point: 1 each (1:29)
Evidence Statement Text: Recognize and represent proportional relationships between quantities.
c. Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expresses as t = pn.
Clarifications, limits, emphases, and other information intended to ensure appropriate variety in tasks:
Tasks have a context.
Tasks use only coordinates in Quadrant 1 and use only a positive constant of proportionality.
