• Creating Equations
A-CED Create equations that describe numbers or relationships.

MGSE9-12.A.CED.3 Represent constraints by equations or inequalities, and by systems of equations
and/or inequalities, and interpret data points as possible (i.e. a solution) or not possible (i.e. a nonsolution)
under the established constraints.

Reasoning with Equations & Inequalities
A-RE I Solve systems of equations

MGSE9-12.A.REI.5 Show and explain why the elimination method works to solve a system of twovariable
equations.

MGSE9-12.A.REI.6 Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.

GA: HS: Functions
Interpreting Functions
F-IF Interpret functions that arise in applications in terms of the context.

MGSE9-12.F.IF.4 Using tables, graphs, and verbal descriptions, interpret the key characteristics of a
function which models the relationship between two quantities. Sketch a graph showing key features
including: intercepts; interval where the function is increasing, decreasing, positive, or negative; relative
maximums and minimums; symmetries; end behavior; and periodicity.
