Another name for linear function, linear equation, line of best fit, goodness of line, least squares regression | Linear Regression |

The way most linear regressions are written - y = mx + b where m is the slope and b is the y-intercept | Slope-intercept form |

When the y increases as the x increases | positive slope |

When the y decreases as the x increases | negative slope |

This is when the y is 0. It's where the line crosses the x-axis | x-intercept |

This is the variable that we have some control over. It's graphed on the x-axis | Independent Variable |

This is the variable that is dependent on another variable. It's graphed on the y-axis | Dependent Variable |

This is when the x is 0 and considered the starting point. It's where the line crosses the y-axis. | y-intercept |

The rate of change, which is a ratio of the change in y's to the change in x's | slope |

Any relationship between two variables | relation |

A special type of relation where every value of the independent variable has one unique value of the dependent variable | function |

A way to indicate that an equation is a function - f(x) | functional notation |

A function whose graph is a single unbroken curve that you could draw without lifting your pencil from the paper | continuous |

A visual test for functions. If you place a vertical line anywhere along the graph of a function , it will only intersect the function once. | Vertical Line Test |

All the real number x-coordinates which can be used as the input of a function | domain |

All the real number y-coordinates which are determined for the outputs of a function | range |
