  1. 6-5 linear inequalities Miss battaglia – algebra 1 CP objective: graph linear inequalities.

  2. “What’s the point?!” • Object of the game: To locate a secret point on the coordinate plane by asking as few questions as possible. • How to Play: • Player A chooses a secret point on the coordinate plane. Each coordinate must be an integer from -10 to 10. • Player B asks questions that contain the words less than or greater than. Player A answers each question with only yes or no. • The players switch roles to complete one round of the game. • How to Win: The player who names the point by asking fewer questions win the round. The first player to win 3 rounds wins the game. (2,-3) Secret Point Is x greater than or equal to 0? Yes

  3. Think & discuss • You can use inequalities to describe regions of a coordinate plane.

  4. A linear inequality describes a region of the coordinate plane that has a boundary line. Every point in the region is a solution of the inequality. Each point on a solid boundary line is a solution Each point on a dashed boundary line is not a solution

  5. Graph • y < 2x + 3

  6. Graph • y > 2x + 3

  7. Graph • 2x – 5y < 10

  8. Graph • y < -1

  9. Graph

  10. Food shopping • A pound of peanuts costs $2 and a pound of cashews costs $4. Suppose you intend to spend no more than $12 on peanuts and cashews for a party. How many pounds of each can do you buy?

  11. Classwork/ homework • Pg292 # 8 – 18
