Intermediate Algebra II Section 1-5(part 1) Notes Template I. Objective: To solve inequalities and graph their solutions. II. Teacher activities: A) Hook: Solve the equation: 4x + 2 = -6 B) Solve inequalities the same way you solve equations. Get the variable to the left, then the shading will go in the same direction as the sign of inequality < or >: open circle at boundary number or: closed circle at boundary number Whenever you multiply or divide both sides of an inequality by a negative value, you must reverse the sign of inequality. Directions: Solve each inequality & then graph the solutions on a number line. The variable MUST be on the LEFT of the inequality symbol.
