    Answer:

    7y = -4 x + 8

    y = -(4/7) x + /7

    so m = -4/7

    y = -(4/7)x + b

    -2 = -(4/7)(4) + b

    -14/7 + 16/7 = b

    b = 2/7

    so

    y = -(4/7)x + 2/7

    7y = -4x + 2

    for the second one

    m = -(-7/4) = 7/4

    so

    y = (7/4) x + b

    now put x = 4 and y = 2 in again to find b
