  1. sundae day! 11.11.22 Pick up the warm-up. Complete. Would you rather become fifteen years older or two years younger? Agenda: • Warm-up • Correct or Incorrect Graphs? • Delta Math Time Pencil, Calculator, Spiral

  2. Inequalities >>>>>>>>>>>>> >>>>>>>>>>>>>

  3. Warm-up: Inequalities in Two Variables Directions: Graph each of the following. Be sure to use a test point to determine the solution region. 1. y > -½ x + 3 2. y + 3 < 2(x + 1) 3. 4x + 2y < -8

  4. Answers Warm-up: Inequalities in Two Variables Directions: Graph each of the following. Be sure to use a test point to determine the solution region. 1. y > -½ x + 3 2. y + 3 < 2(x + 1) 3. 4x + 2y < -8

  7. Correct/Incorrect Directions: • Work with a partner. • Examine each graph. • Determine whether each is “Graphed Correctly” or “Graphed Incorrectly”. • On your recording sheet, write the LETTERS of the ones that are graphed correctly. For the ones that are graphed incorrectly, explain the error that was made.

  8. The boundary line is in the correct location. The line should be solid instead of dashed. The shading is done correctly.

  9. The boundary line is in the correct location. The line is dashed as it should be. The shading is done correctly.

  10. The boundary line is in the correct location. The line is dashed as it should be. The shading is done correctly.

  11. The boundary line is in the correct location. The line should be dashed instead of solid. The shading is done correctly.

  12. The boundary line is in the correct location. The line is dashed as it should be. The shading is done correctly.

  13. The boundary line is in the correct location. The line is solid as it should be. The shading is on the wrong side of the boundary line.

  14. The boundary line is in the correct location. The line is solid as it should be. The shading is done correctly.

  15. The boundary line is in the correct location. The line is dashed as it should be. The shading is done correctly.

  16. The boundary line is in the wrong location. The line is dashed as it should be. The shading is done correctly.

  17. The boundary line is in the wrong location. The line is dashed as it should be. The shading is done correctly.

  18. The boundary line is in the correct location. The line is solid as it should be. The shading is done correctly.

  19. The boundary line is in the correct location. The line is solid as it should be. The shading is on the wrong side of the boundary line.
