Algebra I Unit 6

Big Idea:

Analyze and interpret solutions to systems of equations and inequalities by graphing, writing, and solving the systems.

Student Expectations:

Priority TEKS

A.2(I) [Readiness] write systems of two linear equations given a table of values, a graph, and a verbal description

Focus TEKS

A.3(F) [Supporting] graph systems of two linear equations in two variables on the coordinate plane and determine the solutions if they exist

A.3(G) [Supporting] estimate graphically the solutions to systems of two linear equations with two variables in real-world problems

A.3(H) [Supporting] graph the solution set of systems of two linear inequalities in two variables on the coordinate plane

A.5(C) [Readiness] solve systems of two linear equations with two variables for mathematical and real-world problems

Ongoing TEKS

A.2(H) [Supporting] write linear inequalities in two variables given a table of values, a graph, and a verbal description

A.3(D) [Readiness] graph the solution set of linear inequalities in two variables on the coordinate plane

Student Learning Targets:

• I will solve systems of equations by graphing, substitution, elimination, and evaluating a table of values
• I will interpret solutions of linear systems of equations and inequalities
• I will explain when a system has one solution, infinite solutions, or no solutions.
• I will write a system of equations to model a situation
• I will determine if an ordered pair is a solution to system of equations and system of inequalities.
• I will graph the solution to a system of inequality

Essential Questions:

• How does one determine the most appropriate and efficient strategy for solving a system?
• How would you construct a system of linear inequalities that has only one solution? No solutions? Infinite solutions?
