### Equations of lines, slope, graphs, y-intercept, parallel and perpendicular lines

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

Write an equation in slope intercept form given the following: m = 2, b = -6 | y = 2x - 6 |

Write an equation in slope intercept form given the following: m = -7/5, b = 8 | y = -7/5x + 8 |

Write an equation in slope intercept form given the following. m = 2/3, b = -11 | y = 2/3x - 11 |

Write the equation of a line that has the given slope and passes through the point: m = 5; (-2,-3) | y = 5x + 7 |

Write the equation of a line that has the given slope and passes through the point: m = -2/3; (9,-6) | y = -2/3x + 0 |

Write the equation of a line that passes through the given points: (-5,5) and (1,-1) | y = -1x + 0 |

Write the equation of a line that passes through the given points. (-4,-9) and (-8,0) | y = -9/4x - 18 |

Identify the slope and y-intercept. y = 2/5x + 8 | m = 2/5 b = 8 |

Identify the slope and y-intercept. y = 12x - 1/7 | m = 12 b = -1/7 |

Identify the slope and y-intercept. y = 6/7x | m = 6/7 b = 0 |

Identify the slope and y-intercept. y = 3 | m = 0 b = 3 |

Identify the slope and y-intercept. y = 5 + 3/4x | m = 3/4 b = 5 |

Identify the slope and y-intercept. x = 13 | m = undefined b = |

rise over run = | slope |

line goes up as you move from left to right | positive |

line goes down as you move from left to right | negative |

line remains flat as you go from left to right | zero slope |

vertical lines slope | undefined |
