xy=c
here x and y are the variables and c denotes the constant

the variation can be expressed as
x=c.y

Taking an example:

1) assigning a fixed number to c (as c is constant)
eg: c=2

the variation becomes
x=2y

2) assigning values to y

  • y=1 ,then x=c.y=2.1,x=2
  • y=2,x=2.2,x=4

There is a direct variation between y and x , as y goes on increasing, so does x.
So basically x varies in the same manner as y

Looking at a more practical example.
Distance= (Speed)x(Time)

here as speed increases the distance covered would also be greater.
