Slope | of a straight line shows how steep a straight line is. |

x-intercept | The value of x when a given curve crosses the x-axis |

y-intercept | The value of y when a given curve crosses the y-axis. |

Unit Rate | is the ratio of two measurements in which the second term is 1. |

Constant of Proportionality | the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality |

Direct Variation | A relationship between two variables such that the values of both variables increase or decrease together at a constant rate. |

Linear Equation | An equation in which the highest power of any variable is one. |

Point-Slope Form | The equation of a straight line in the form y-y1= m (x-x1), where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line in a cartesian coordinate system. |

Slope-intercept form | coordinate system, the equation of a straight line in the form y = mx + b, where m is the slope of the line and b is its intercept on the y axis. |
