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

ordered pair | a pair of numbers used to locate a point in a coordinate plane. the first number is the y-coordinate. |

coordinate plane | a plane is formed by the intersection of a horizontal number line, usually called the x-axis, ans a vertical number line, usually called the y-axis. |

x-axis | the horizontal number in a coordinate plane. |

y-axis | the vertical number line in a coordinate plane. |

x-coordinate | the first coordinate in an ordered pair, which indicates how many units to move to the left or right from the origin. |

y-coordinate | the second coordinate in an ordered pair, which indicates how many units to move up or down from the origin. |

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

solution of a linear equation | a value that make an equation true. |

slope | a ratio of the change in y to the change between any two points on the line. it is a measure of the steepness of a line. |

rise | the change in y between two points on a line |

run | the change in x between two points on a line |

slope - intercept form | an equation written in the form y = mx + b. the slope of the m and y int of the line is b. |

x-intercept | the x coordinate of the point where a line crosses the x axis |

y-intercept | the vertical number line in a coordinate plane. |

standard form | a linear equation written in the form ax + by = c, where a and b are not both zero. |

systems of linear equations | a set two or more linear equation in the same variables. |

solutions of a systems of linear equations | an ordered pair that makes each equation in a system of linear equation true. |
