COURSE 2 LESSON 2 -8 Graphing and Writing Inequalities Tell whether each number is a solution of k > – 6: – 8, – 6, 0, 3, 7. – 8 > – 6 with each number. false 0 > – 6 3 > – 6 true 7 > – 6 true The numbers 0, 3, and 7 are solutions of k > – 6. The numbers – 8 and – 6 are not solutions of k > – 6. 2 -8 Replace k

COURSE 2 LESSON 2 -8 Graphing and Writing Inequalities Graph the solution of each inequality on a number line. a. r < – 2 Use a closed circle at 2 to show that r can equal 2. b. a > – 0 Use a closed circle at 0 to show that a can equal 0. c. j < 1 Use an open circle at 1 to show that j cannot equal 1. d. m > – 5 Use an open circle at – 5 to show that m cannot equal – 5. 2 -8

COURSE 2 LESSON 2 -8 Graphing and Writing Inequalities Write an inequality for each graph. a. y > – – 1, use Since the circle at – 1 is closed, use < –. – or > . Since the graph shows values equal to or greater than > – Since the circle at – 4 is open, use < or >. b. z < – 4 Since the graph shows values less than – 4, use <. 2 -8

COURSE 2 LESSON 2 -8 Graphing and Writing Inequalities You must be at least 18 years of age to vote in a presidential election in the United States. Write an inequality for this requirement. Words age Let Inequality is a greater than or equal to 18 years = age in years. > – a The inequality is a > – 18. 2 -8 18

Graphing and Writing Inequalities Write an inequality for each verbal statement. Graph the solution. COURSE 2 LESSON 2 -8 1. A dog weighs less than 25 pounds. d < 25 2. You must be at least 18 to vote. v > – 18 2 -8
