### Unit 3 Linear Equations and Functions Vocabulary

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

Constant of Proportionality | is the value that relates the two amounts |

Slope | A rate of change/measure of the steepness of a line |

Direct Variation | A relationship between two variables in which one is a constant multiple of the other |

X- intercept | a zero, also sometimes called a root, of a real-, complex- or generally vector-valued function |

linear equation | an equation between two variables that gives a straight line when plotted on a graph. |

Y- Intercept | In coordinate geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept is a point where the graph o |

Point-Slope Form | the equation of a straight line |

Unit Rate | A rate whose denomater equals one |

Slope- intercept form | A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable. |

Proportional Relationship | Two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other. |

Rate of Change | Momentum and rate of change are simple technical analysis indicators |
