Hi

*Note: When Quantities vary directly,they are related by the relationship:

 y+=+%28kx%29 k being  the constant of proportionality.

Suppose x varies directly with y. If y increases by a factor of 2, 

what will happen to x...it will increase by a factor of 2

  x = ky    k being constant or always the same value

 2x = k(2y)
