### Rational Exploration:Numbers and their Opposites

Term | Definition |
---|---|

Absolute value | The distance between a number and zero on the number line. |

Cartesian Coordinate Plane | A plane containing two perpendicular axes (x and y) intersecting at a point called origin (0,0). |

Coordinates | An ordered pair, (x,y) that locates a point in a plane. |

Distance | Amount of separation between 2 points. |

Integers | The set of whole numbers and their opposites {...-3,-2,-1,0,1,2,3...}. |

Magnitude | Greatness in size or amount |

Negative numbers | The set of numbers less than zero |

Opposite number | Two different numbers that have the same absolute value. Example: 4 and -4 are opposite numbers because both have an absolute value of 4. |

Ordered Pair | A pair of numbers, (x,y) , that indicate the position of a point on the Cartesian coordinate Plane. |

Origin | The point of intersection of the vertical and horizontal axes of a Cartesian coordinate plane. The coordinates of the origin are (0, 0). |

Positive number | The set of numbers greater than zero. |

Quadrant | One of the four regions on a Coordinate plane formed by the intersection of the x-axis and the y-axis. |

Rational number | The set of numbers that can be written in the form a/b where a and b are integers and b is not equal to 0. |

Sign | a symbol that indicates whether a number is positive or negative. Example: in -4, the (-) sign hows this number is read “negative four”. |

x-axis | The horizontal number line on the Cartesian coordinate plane. |

x-coordinate | The first number of in ordered pair; the position of a point relative to the vertical axis |

y-axis | The vertical number line on the Cartesian coordinate plane |

y-coordinate | The second number in an ordered pair; the position of a point relative to the horizontal axis |
