    for first question
    a.y=-6x-48
    b.y=6x-48
    c.y=-12x-42
    d.y=-12x-54

    Sorry -- I don't know.

  • algebra 1 -

    a isn't right.
    y-6 = -12(x+4)
    y-6 = -12x - 48
    y = -12x -48+6
    y = -12x - 44

  • algebra 1 -

    ...
    y-6 = -12x - 48
    y = -12x -48+6
    y = -12x - 42

  • oops--algebra 1 -

    Better review my subtraction rules.
