Linear Functions

This unit includes linear equations, inequalities, and systems.  There should be an emphasis on the connection between the 5 representations: graph, table, problem situation, pictorial, symbolic.  Within this unit, connections to foundations for functions and how all functions have same traits should be made.

Objective TEKS TEKS Clarification TAKS Objectives SATEC Lesson/Resource(s) SATEC Correlated Assessment Dana Center Assessments Resources/Text
Formulate linear functions from a given situation.  

Revisit data activity from Foundations for Functions and reinforce common function characteristics.
 

Revisit data to extend the discussion of linear functions to writing equations, graphing and translating functions, analyzing parameter changes in the context of the situation.
 

Write and graph linear equations in the y=mx + b form, including transforming from Ax + By = C to y = mx + b.
 

Graph lines from Ax + By = C using x and y-intercepts.
 

Write equations of parallel and perpendicular lines.
 

Review solving one-variable equations and inequalities as needed.
 

Graph two-variable inequalities.
 

Write and solve equations and inequalities from application problems.
 

Solve systems using graphs, algebra, and matrices. * Use inverse matrices as a tool to solve systems with technology; this is not to be an in-depth look at matrices, therefore a minimal amount of time should be spent on matrix operations.
 

Use technology such as graphing calculators and/or computers to link multiple representations
