Use units as a way to understand real-world problems.*
A2.A.CED.A.1
Create equations and inequalities in one variable and use them to solve problems in a real-world context.*
A2.A.CED.A.2
Create equations in two variables to represent relationships between quantities and use them to solve problems in a real-world context. Graph equations with two variables on coordinate axes with labels and scales, and use the graphs to make predictions.*
A2.A.REI.A.1
