4 Lets think ……… 1,0,-1,-2,-3… What about… ½ or ? This is why we use an open circle when we graph the inequality x< 2 Is 2 less than 2?

5 The open circle tells us that 2 is not included

6 Graph x > 2 Where do we put the circle ? In which direction does the arrow go? Think…what could you plug in for x that is greater than 2?

7 What about x 2 ……is 2 2 Which way does the arrow go?

8 What about x 2 ……is 2 2 Which way does the arrow go? Where do we put the circle ?

9 1.Write the inequality above the number line. 2.Graph the inequality. 1) x > 8 2) x< 7 3) x 4 4) x -3 5) x < -5 6) x 6
