Solve the following inequalities and draw a number line graph to represent each solution. Homework Help ✎

a. Solve the corresponding equations to determine the boundary points. Solving yields Plot these points on a number line. Test a point in each region on the number line in the original inequality. Highlight the region(s) where the test point makes the inequality true. | b. See the steps in part (a). The boundary points in part (b) are the same as the ones in part (a). When you test a value between the boundary points you get a false statement. |

c. See the steps in part (a). | d. |

e. | f. |

g. Describe any relationships you see among these six problems. How are the graphs of the 'less than' inequalities related to the graphs of the 'greater than or equal to' inequalities? |
