Question | Answer |
---|---|

slope y-intercept | y=mx+b |

standard form | Ax+By+C=0 |

slope equation | y2-y1/x2-x1 or for a graph rise/run |

fixed number | y-intercept |

variable number/constant multiple/ constant of variation | slope |

m= | slope |

b= | y-intercept |

horizontal lines | slope is zero, slope in equation is y=0x+b, y=b is the equation |

vertical lines | slope doesn't exist=undefined, can't use slope y-intercept for vertical lines, written in the form x=a where a is the x-intercept |

direct variation | passes through the origin (0,0) y=mx |

partial variation | doesn't pass through the origin (0,0) y=mx+b |

linear | points form a straight line, first differences are constant |

non-linear | points don't form a straight line, first differences aren't constant |

linear system | a set of two or more linear equations that are considered simultaneously |

point of intersection | the point where two (or more) lines cross |

two parallel lines | never cross, no common points, no solution |

two non-parallel lines | intersect at one point, one solution |

two identical lines | equation different but same line, infinite number of solutions |

parallel lines | lines which run in the same direction and never cross |

perpendicular lines | lines which intersect at right angles (90o) |

how to know if two equations are parallel | they have equal slopes |

how to know if two equations are parallel | the slopes are negative reciprocals |

x-intercept | the value of x where the line crosses the x-axis (y=0) |

y-intercept | the value of y where the line crosses the y-axis (x=0) |
