SECTION 3.2: LINEAR INEQUALITIES A. GRAPHING LINEAR INEQUALITIES An algebraic inequality is a mathematical sentence connecting an expression to a value, variable, or another expression with an inequality sign. Below is a table of inequalities we will be using . Symbol In Words Examples < less than 1 < 2 “1 is less than 2”
