MA19.7A.20
Represent constraints by equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context. Limit to contexts arising from linear. [Algebra I with Probability, 13 partial]

Unpacked Content

Knowledge

Students know:

How to construct a linear function that models the relationship between two quantities.
how to graph two variable equations using appropriate scale.
how to interpret a graph of two variable equations in context.

Skills

Students are able to:

Write and graph a system of linear equations or inequalities based on real-world context.
Interpret the solutions to equations or inequalities as a viable or nonviable answer based on models created from the equations or inequalities.

Understanding

Students understand that:

The solutions to linear systems of equations/inequalities, while sometimes infinite in theory, can be limited to have more realistic meaning in real-world contexts.
