    Y = kx, where k is the constant of proportionality.

    We need to find k as our first step.

    35 = k140

    35/140 = k

    1/4 = k

    We can now find y when x = 70.

    y = kx

    y = (1/4) (70)

    y = 70/4

    This fraction can be simplified or reduced more.

    The number 2 is the GCF of 70 and 4.

    70 : 2 = 35

    4 : 2 = 2

    Answer:

    y = 35/2
