    k = 6.78

    Step-by-step explanation:

    If two variables x and y are respectively the independent and dependent variables and they are proportional to each other, then we can write the mathematical expression as y ∝ x.

    This gives, y = kx ... (1)

    Where k = proportionality constant.

    Now, we are given a linear equation of x and y and we have to get the constant of proportionality.

    The given equation is y = 6.78x ... (2)

    Now, comparing equation (1) and (2) we get k = 6.78. (Answer)
