Question

Which relation is a partial variation

A) y=25x

B)y=2x

C) y =5x2

D) y=2x-5

Answer 1

D) y = 2x - 5

Explanation:

A partial variation is defined as a relation which has the form
`y=mx+b`, where
`m` is the slope and
`b` is the y-intercept.

So, by definition, the right answer is D) y=2x-5, it's a partial variation, and it doesn't pass through the origin of the coordinate system.
