    Answer:

    The same ratio indicates that there is a proportional relationship between y and x.

    Step-by-step explanation:

    We know when y varies directly with x, the equation is

    y ∝ x

    y=kx

    k\:=\:\frac{y}{x}

    Here,

    k is the constant of proportionality.

    The ratio y/x indicates that k is a constant of proportionality.

    Thus, the same ratio indicates that there is a proportional relationship between y and x.

    When x increases, y increases, and when y decreases, x also decreases.
