The lines we wish to draw correspond to the boundaries of the region:

x | + | 2y | ≤ | 16 | equa / explicit | y = | (16-x ) / 2 |

x | + | y | ≤ | 9 | equa / explicit | y = | 9-x |

3x | + | 2y | ≤ | 24 | equa / explicit | y = | ( 24 - 3x ) / 2 |

x | ≥ | 0 | equa / line | x = | 0 | ||

y | ≥ | 0 | equa / explicit | y = | 0 |
