    B. Neither

    The slope of the first equation is m=6/7. To have the second equation parallel to the first, it must have the same slope of 6/7. To make it perpendicular, it should have a negative reciprocal slope of - 7/6. Unfortunately, the second equation does not qualify on both conditions.
