Linear algebra incorporates variables, where one depends on the other as part of a coordinate system that can be two-dimensional (2-D like a picture) or three-dimensional  (3-D like an image with the perception of depth, a model or an animation. 

Algebraic concepts and linear algebra are useful in graphics, computer assisted design and animation. In addition, algorithms and graphing using linear algebra are related to the separation and clustering of related data points and creating categories. 

This CCR-aligned formative assessment set of activities was created as part of the The FASt project through the New England Literacy Resource Center to create and use  CCR-aligned formative assessments.  Project handouts and teacher-developed formative assessments for ESL, ELA, and math can be found on the FASt page. (The resource can be found on the FASt page and downloaded as a document under the title "Lyn Michaud Smith, Eastern Aroostook Adult and Continuing Education – A rubric/study guide for interpreting functions."  or as a shared Google Doc A rubric/study guide for interpreting functions.

This activity pairs well with this lesson for solving linear equations.
