    Neither

    Step-by-step explanation:

    5 x - 10 = - 50

    4 x 9 = 36

    -50 + 36 = - 14 and therefore can not be orthogonal

    sqrt (25+16) = sqrt (41)

    sqrt (100+81) = sqrt (181)

    sqrt (41) x sqrt (181) is not equal to - 14 so therefore it is not parallel

    So the answer is then neither
