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

ordered pair | a pair of numbers that can be used to locate a point on a coordinate plane. |

coordinate plane | a plane formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis. |

x-axis | the horizontal axis on a coordinate plane |

y-axis | the vertical axis on a coordinate plane |

x-coordinate | the first number in an ordered pair |

y-coordinate | the second number in an ordered pair |

origin | the intersection of the x-axis and y-axis. The point (0,0) |

graph of an equation | the set of all ordered pairs that are solutions of the equation |

function | a rule that relates two quantities so that each input value corresponds to exactly one output value. |

input | the value substituted into an expression or function |

output | the value that results from the substitution of a given input into a function |

domain | the set of all possible input values |

range | the set of all possible output values |

vertical line test | A test used to tell if a graph is a function. If a vertical line intersects the graph at only one point, then the relationship is a function. |

sequence | an ordered list of numbers or objects |

term | an element or number is a sequence |

arithmetic sequence | an ordered list of numbers in which the difference between consecutive terms is always the same |

common difference | the difference between nay two successive terms in an arithmetic sequence |
