Answer 1

Direct variation

Explanation:

Given

`(a_1)/(b_1) = (a_2)/(b_2)`

Required

The type of variation

The given equation represents a direct variation.

A direct variation is:

`a = kb`

Where

`k\to` constant of variation

Make k the subject

`k = (a)/(b)`

For corresponding values of and b, we have:

`k = (a_1)/(b_1) = (a_2)/(b_2) = (a_3)/(b_3) = ............. =(a_n)/(b_n)`

Hence,
`(a_1)/(b_1) = (a_2)/(b_2)` is a direct variation
