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

Axes | Two perpendicular number lines that are used to locate points on a coordinate plane |

Complete graph | Show the origin, the points at which the graph crosses the x-axis and y axis and other important characteristics of the graph |

Completeness property for points in the plane | exactly one point in the plane is named b a given ordered pair of numbers |

Coordinate plane | the plane containing the x and y axes |

Domain | the set of all first coordinates from the ordered pairs in a relation |

Equation in two variables | an equation that contains two unknowns |

Function | a relation in which each element of the domain is paried with exactly one element of the range |

Function notation | The equation y=x+5 written as f(x) = x+5 |

Graph | to draw, or plot, the points named by certain numbers or ordered pairs on a number line or coordinate plante |

Interquartile range | the difference between the upper and the lower quartile in a set of data |

inverse of a relation | obtained by switching the coordinates in each ordered pair |

linear equation | an equation whose graph is a straight line |

linear equation in standard form | can be written in the form Ax + By = C |

linear function | an equation whose graph is a nonvertical line |

lower quartile | divides the lower half of a set of data into two equal parts |

mapping | pairs one element in the domain with one element in the range |

origin | the point of intersection of the two axes in the coordinate plane |

outlier | a value that is much greater or much less than the rest of the data in a set of data |

quadrants | one of the four regions into which teh x- and y-axes separate the coordiante plane |

quartiles | values that divide the date into four equal parts |

range (when dealing with a relation) | the set of all second coordinates from the ordered pairs in the realation |

relation | a set of ordered pairs |

solution of an equation in two variables | if a true statement results when the nubmers in an ordered pair are substituted into an equation |

upper quartile | divides the upper half of a set of data into two equal parts |

verticle line test | if any verticle line passes through no more than 1 point of the graph of a relation, the relation is a function |

x-axis | the horizontal number line |

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

y-axis | the verticle number line |

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

use a table | a problem-solving strategy that uses tables to organize and problem solve |
