# Coordinate Planes

Question | Answer |
---|---|

This is formed when 2 perpendicular lines intersect | coordinate plane |

This is the horizontal axis | X- axis |

This is the vertical axis | Y-axis |

The point where the two axes intersect (0,0) | origin |

A pair of numbers that is used to name a point | ordered pair |

What is needed to write an ordered pair? | parentheses, the x-coordinate, a comma and the y-coordinate |

The y- coordinate is 8 and the x-coordinate is 4. How would you write the ordered pair? | (4,8) |

An ordered pair is (3,3). If the y-coordinate was moved up 2 units, what would the new ordered pair be? | (3,5) |

An ordered pair is (6,7). If the x-coordinate was moved down by 4 units, what would the new ordered pair be? | (2,7) |

An ordered pair is (3, 8). If the x-coordinate was moved to the right by one unit, what would the new ordered pair be? | (4,8) |
