Parts of Linear Inequalities

The relation of two expressions using the symbols <, >, ≤, ≥, or ≠ and whose boundary is a straight line. The line divides the coordinate plane into two parts.

• Linear Inequality

• Linear Equation

• System of Linear Inequalities

Two or more linear inequalities with the same variables.

• System of Linear Inequalities

• System of Linear Equations

• Graphing

Two or more inequalities using the same variables.

• Matrix

• System of Inequalities

• System of Equations

• Linear Inequalities

An inequality in forms Ax+By>C, Ax+By>C, Ax+By<C or Ax+By<C - and A, B, and C are constants.

• linear inequality

• inconsistent equation

• linear system

• boundary line

• Lars meets both of his expectations

• Lars works for the expected number of days but doesn't earn the expected number of money

• Lars earns the expected amount of money but doesn't work for the expected number of days

• Lars doesn't meet either of his expectations

• Astrid meets both of her expectations

• Astrid buys the expected number of fruits, but she does beyond her budget

• Astrid stays within her budget, but she doesn't buy the expected number of fruits

• Astrid doesn't meet either of her expectations

Lars meets both of his expectations

• Lars meets both of his expectations

• Lars works for the expected number of days but doesn't earn the expected number of money

• Lars earns the expected amount of money but doesn't work for the expected number of days

• Lars doesn't meet either of his expectations

Consists of two or more linear inequalities with the same variables.

• system of linear inequalities

• linear system

• coincident lines

• solution region

Represents ALL solutions of a system; part of the coordinate plane; ordered pairs in this area are solutions to the inequalities in the system.

• boundary line

• parallel line

• consistent systems

• solution region

An ordered pair (x,y) that makes the inequality TRUE

• independent system

• solution region

• solution to linear inequality

• substitution solution
