CCSS.Math.Content.7.RP.A.2 Recognize And...

CCSS.Math.Content.7.RP.A.2 - Recognize and represent proportional relationships between quantities.


CCSS.Math.Content.7.RP.A.2.a - Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.


CCSS.Math.Content.7.RP.A.2.b - Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.


CCSS.Math.Content.7.RP.A.2.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 expressed as t = pn.


CCSS.Math.Content.7.RP.A.2.d - Explain what a point (x,y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1,r) where r is the unit rate.
