Answer:

see below

Step-by-step explanation:

27) y = kx

     18 = k(20)

     18 = 20k

      k = 0.9

28) y = kx

     -9 = k(3)

     -9 = 3k

       k = -3

     

     y = -3x

29a) y = kx

     5 = k(1/3)

     5 = 1/3k

     k = 15

    y = 15x                      

29b) y = 15x

        y = 15(-2)

        y = -30
