    9x + 3y = - 22 |subtract 9x from both sides

    3y = - 9x - 22 |divide both sides by 3

    y = - 3x - 22/3

    The line parallel to the line y = - 3x - 22/3 has that same a slope.

    Therefore your answer is B) y = - 3x + 8.

    9x + 3y = - 22

    3y = - 9x - 22

    y = - 3x - 22/3

    slope m=-3

    lines are parrallel when m1=m2

    m1=-3

    Y = - 3x + 8

    m2=-3

    s0 B is right option
