Find the x and y intercepts: x + y = -7 | X intercept = -7 y intercept = -7 |

Find the x and y intercepts: 3x + y = 12 | X intercept = 4 y intercept = 12 |

Find the x and y intercepts: 5x + 4y = 40 | X intercept = 8 y intercept = 10 |

Find the x and y intercepts: x-2y = 6 | X intercept = 6 y intercept = -3 |

Find the x and y intercepts: -4x + y = -8 | X intercept = 2 y intercept = -8 |

Find the x and y intercepts: 2x -2y = 10 | X intercept = 5 y intercept = -5 |

Advanced tickets (x) cost $4.00, Tickets bought at the door cost (y) $6.00. Total brought in $240. Write an equation to represent the number of tickets sold. | $4.00x + $6.00y = $240 |

Advanced tickets (x) cost $4.00, Tickets bought at the door cost (y) $6.00. Total brought in $240. Find the x and y intercepts. | x intercept = 60 tickets (this means all advanced ticekts- no door tickets) y intercept = 40 tickets (this means all door, no advanced) |

Advanced tickets (x) cost $4.00, Tickets bought at the door cost (y) $6.00. Total brought in $240. If 15 advanced ticket were sold, how many were bought at the door. | $4 (15) + 6y = 240, 60 + 6y = 240, 6y = 180 y= 30 tickets |

Which point lies on the graph: 4x + y = 8 (1, 7) or (0, 8) | (0,8) |

Which point lies on the graph:x = -3 (-3, 1) or (4, -3) | (-3,1) |

Which point lies on the graph: 4y - 6x = 0 (2, 3) or (-2, 3) | (2,3) |

Which point lies on the graph: 5x+ 2y = 10 (3, 1)or (0,5) | (0,5) |

Rewrite in function form (Solve for y) : -5x +y = 7 | y = 5x + 7 |

Rewrite in function form (Solve for y): 8x -2y = 10 | y = 4x -5 |

Rewrite in function form (Solve for y): -6x + 9y = 9 | y = 2/3x + 1 |

Rewrite in function form (Solve for y): -3x + 3y = 9 | y= x + 3 |
