Answer 1

Answer: 11. (4,0) 13. (2,-2)

Explanation:

11.

`\displaystyle\\\left \{ {{y=(1)/(2) x+7 } \atop {y=(3)/(2)x+3 }} \right. \\\\y=(1)/(2)x+7`

x | 0 | 4 |

y | 7 | 9 |

`\displaystyle\\y=(3)/(2)x+3\\`

x | 0 | 2 |

y | 3 | 6 |

13.

`\displaystyle\\\left \{ {{y=x-4} \atop {y=-x}} \right. \\\\y=x-4`

x | 0 | 4 |

y | -4 | 0 |

`y=-x`

x | 0 | 4 |

y | 0 | -4 |
