Algebra II Unit 1

Big Idea:

Solve systems of equations/inequalities and solve absolute value equations/inequalities.

Student Expectations:

Priority TEKS

2A.3(A) formulate systems of equations, including systems consisting of three linear equations in three variables and systems consisting of two equations, the first linear and the second quadratic

2A.3(E) formulate systems of at least two linear inequalities in two variables

2A.3(F) solve systems of two or more linear inequalities in two variables

2A.6(E) solve absolute value linear equations

2A.6(F) solve absolute value linear inequalities

Focus TEKS

2A.3(B) solve systems of three linear equations in three variables by using Gaussian elimination, technology with matrices, and substitution

2A.3(G) determine possible solutions in the solution set of systems of two or more linear inequalities in two variables

2A.6(D) formulate absolute value linear equations

Student Learning Targets:

• I will create and solve an equation in one variable from a real world context
• I will create and graph equations in two variables to represent relationships between quantities
• I will write, solve, and graph absolute value equations and inequalities
• I will represent constraints by equations or inequalities by using a graph to determine solutions of a system of inequalities
• I will use various methods to solve systems of linear equations in 2 or 3 variables
• I will use technology to perform operations on matrices

Essential Questions:

• How do you determine which method is most appropriate and/or most efficient for solving a particular system of equations?
• How are linear equations and systems of equations and inequalities used to model and solve real-world problems?
• How can systems of equations predict future behavior of real-world situations?
