  2. Graphing Inequalities

  3. The Solution of An Inequality is… • Any value of the variable that makes the inequality true • It is easier to understand the solution once it is graphed on a number line • MUST be written as a complete mathematical sentence (x > 5 rather than just 5)

  4. Inequality Symbols • > means greater than • > means greater than or equal to • < means less than • < means less than or equal to • means not equal to

  5. Graphing Greater Than • Use an open circle • Shade to the right • Put an arrow at the end of the shading

  6. Graphing Greater Than or Equal • Use a colored in circle • Shade to the right • Put an arrow at the end of the shading

  7. Graphing Less Than • Use an open circle • Shade to the left • Put an arrow at the end of the shading

  8. Graphing Less Than or Equal To • Use a colored in circle • Shade to the left • Put an arrow at the end of the shading

  9. Graphing Not Equal To • Use an open circle • Shade both directions • Put an arrow at the both ends of the shading

  10. Graphing Equal To • Use a colored in circle • No shading

  11. And now… • Assignment #14 pages 177 – 179 (25 – 53 odd) AND pages 183 – 185 (51 – 83 eoo) • Test corrections are due on Monday, September 26th. • Why? Because that is the NEXT test!
