Hi
*Note: When Quantities vary directly,they are related by the relationship:
 {{{y = (kx)}}} 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)
