  4. 4. 3b + 2.4w < 24 back burger and wing purchase 10 9 8wings 7(pounds) 6 5 4 3 2 shade the 1 half plane 1 2 3 4 5 6 7 8 9 10 burger (pounds)
  5. 5. 3b + 2.4w < 24 burger and wing next purchase 10 9 8wings 7(pounds) 6 5 4 click on my spatula, then click on the half-plane you think should be shaded to 3 make the inequality correct. 2 1 1 2 3 4 5 6 7 8 9 10 burger (pounds)
  6. 6. 3b + 2.4w < 24 questions burger and wing purchase 10 9 8wings 7(pounds) 6 5 4 3 2 1 1 2 3 4 5 6 7 8 9 10 burger (pounds)
  7. 7. to the graph·can you buy 6 lbs of burger and 4 lbs wings if you want to stay within your setbudget?·how many pounds of wings can you buy if you decide not to buy any burger?·if you buy 3 lbs of burger, what is the most whole pounds of wings you canbuy? to Menu
  8. 8. Inequalities on a plane·review of graphs >
  9. 9. graph the inequality on your paper, then slide the arrow to check y>x y > -x next slide
  10. 10. drag the key word to the matching inequality columnincorrect answers will "disappear" < > at most no more than at least less than or equal to greater than or equal to no next less than
  11. 11. Match the inequality to the graphnote: > is written as >= < is < = next
  12. 12. touch the graph that correctly shows: y < -3x + 4 next
  13. 13. touch the graph that correctly shows: y > 4 x - 6 3
