  • 3. Inequalities and their Graphs What is a good definition for Inequality?An inequality is a statement thattwo expressions are not equal 2 3 4 5 6 7 8
  • 4. Inequalities and their GraphsTerms you see and need to knowto graph inequalities correctly< less than Notice open> greater than circles
  • 5. Inequalities and their Graphs Terms you see and need to know to graph inequalities correctly≤ less than or equal to≥ greater than or equal to Notice colored in circles
  • 6. Inequalities and their GraphsLet’s work a few together Notice: when variable is on left side, sign showsx >3 direction of solution 3
  • 7. Inequalities and their GraphsLet’s work a few together Notice: when variable isx<7 on left side, sign shows direction of solution 7
  • 8. Inequalities and their GraphsLet’s work a few together Notice: when variable isp ≤ −2 on left side, sign shows direction of solution -2 Color in circle
  • 9. Inequalities and their GraphsLet’s work a few together Notice: when variable isx≥8 on left side, sign shows direction of solution 8Color in circle
