3. Warm Up

4. Example 1 Check whether the ordered pair is a solution of 2x – 3y > -2 a.(0,0) 2(0)-3(0)> -2 0> -2 True b.(0,1) 2(0)-3(1)> -2 -3> -2 False c.(2,-1) 2(2)-3(-1)> -2 7> -2 True

5. Toolkit Graphing Inequalities

6. Example 2 Graph x<-2 x < -2 is a vertical line. Dashed Check (0,0) 0<-2 false

7. Example 3 graph y< 1 y < 1 is a horizontal line. Solid Check (0,0) 0 < 1 true
