  1. Solving Inequalities Lesson 2-9 & 2-10

  2. Math Vocabulary Review Inequality: A math sentence that compares (<, >, <, >) a point/points on a number line

  3. Review of Graphing Inequalities • Graph the given point of the inequality • PointsSymbol(s) • (closed) > OR < ◦ (open) > OR < • Determine what side of symbol the variable is on… “small” point OR “big” open • Choose a number to match the symbol side of variable • Graph solutions (arrow) in that direction m > -4

  4. Solving Inequalities +/- Similar to solving equations: Opposite Integer Math 3 < r + 6 - 6 - 6 -3 < r Graph: ___________________________________________

  5. Solving Inequalities +/- y – 14 < -26 + 14 +14 y < -12 Graph: ___________________________________________

  6. Practice Solve & Graph each inequality: • 8 + t <15 ___________________ • v – 4 < 7 ___________________ • t – 5 >11 ____________________

  7. Solving Inequalities x / ÷ 3y <-18 y < -6 Graph: _____________________________________ b > 3 4 b > 12 Graph: ______________________________________

  8. Solving Inequalities x / ÷ (w/ negatives) When “doing math” with negatives -3y < -18 y > 6 Graph: ______________________________________ b > 3 -4 b < -12 Graph: _______________________________________

  9. Practice Solve & Graph each inequality: • 4x< 40 • 36 > -9t • m >2 4 • 5 < r -3

  10. Homework p. 106-109 #3-6, 8, 10, 12, 16, 18, 20, 25-27, 37-39
