relation | a _____ maps the domain elements to the rage elements |

dependent | the variable graphed on the vertical axis, output |

discreet data | a function in the form of y=mx+b |

point slope | the form of a linear equation that shows the slope of the line and one point on the line. |

continuous data | numbers between any two data points have meaning |

range | the output values of a mathematical relation |

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 of a function or relation intersects with the y-axis of the coordi |
