Comprehensive Study Guide to Systems of Linear Equations and Inequalities

Vocabulary flashcards covering Unit 4 concepts, including methods for solving systems of equations, graphing linear inequalities, and puzzle objectives from Algebra with Pizzazz!.

Objective 2-h

A learning objective from Algebra with Pizzazz! (page 197) focused on graphing linear inequalities in two variables where the inequalities are solved for $y$.

Objective 2-j

A learning objective from Algebra with Pizzazz! (page 200) focused on solving systems of linear inequalities in two variables by graphing.

Boundary Line

The line bordering the solution region of a linear inequality, which is either included in the solution (solid line) or excluded from the solution (dotted line).

Solution Set of a System of Inequalities

The common region of points on a coordinate plane satisfying all inequalities in a system simultaneously, visually indicated by crosshatching or shading.

Crosshatching or Shading

The graphical method used to highlight and display the intersection of regions representing the solution set of a system of linear inequalities.

Quadrants (I, II, III, IV)

The four sections of a coordinate plane used to identify the spatial extent and location of an inequality's shaded graph.

Solving Systems of Equations by Graphing

A unit topic scheduled on 10/21 and 10/29 that involves plotting equations on a coordinate plane to find their point of intersection.

Solving Systems of Equations by Substitution

An algebraic method covered in Lesson 4-1 (scheduled on 10/22, 10/23, and 10/28) where one equation is solved for a variable and substituted into another equation.

Solving Systems of Equations by Elimination

An algebraic method for solving systems of linear equations scheduled for instruction and practice on 10/30 and 11/5.

Linear Inequalities in Two Variables

The unit topic introduced on 11/6 that expands algebraic relationships from linear equations to two-variable inequality relationships.

Algebra with Pizzazz!
