Algebra I Unit 5

Big Idea:

Use linear inequalities to represent situations by graphing and interpreting solutions.

Student Expectations:

Focus 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

Ongoing TEKS

A.2(A) [Readiness] determine the domain and range of a linear function in mathematical problems; determine reasonable domain and range values for real-world situations, both continuous and discrete; and represent domain and range using inequalities

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

A.3(C) [Readiness] graph linear functions on the coordinate plane and identify key features, including x-intercept, y-intercept, zeros, and slope, in mathematical and real-world problems

Student Learning Targets:

• I will understand there are infinite solutions to inequalities
• I will understand and identify the significance of each type of boundary line of inequality graphs.
• I will write and graph inequalities to represent real-world situations.
• I will write linear inequalities in two variables from multiple representations.
• I will read and interpret graphs of linear inequalities

Essential Questions:

• Why would you use multiple representations of linear equations and inequalities?
