Question

What kind of variation is `x/y=c`?

Answer 1

`x/y=c`
here `x` and `y` are the variables and `c` denotes the constant

the variation can be expressed as
`color(red)(x) = c . color(green)(y`

Taking an example:

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

the variation becomes
`color(red)(x) = color(blue)(2 color(green)(y`

2) assigning values to `y`

• `color(green)(y = 1` ,then `x= c.y = 2.1 , color(red)(x= 2`
• `color(green)(y=2),x = 2.2, color(red)(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.
