    x ∝ y

    x = 12/7y

    Step-by-step explanation:

    Direct Proportion = x ∝ y

    x = ky where k is the constant.

    Substitute the values in:

    60 = 35k

    Now solve for k.

    60/35 = k

    k = 12/7

    x = 12/7y

    As the value of x increases the value of y increases proportionally.
