    Answer:

    y = 6

    Step-by-step explanation:

    We need to interpret the question

    y varies directly as x

    y varies x

    To equate it, we need to add a constant K

    y = K/x

    Using the information we are provided with

    y = 9

    x = 3/2

    insert into

    y = Kx

    9 = K * 3/2

    9 = 3K/ 2

    3K = 9 *2

    3k = 18

    To get K, divide through by 3

    3K/3 = 18/3

    K = 6

    Since we’ve gotten our K = 6

    y = Kx

    Using the new information

    y = ?

    x = 1

    K = 6

    y = 6* 1

    y = 6

    The new y = 6 , x =1
