Question

Which relation is a partial variation

Answer 1

Answer:

D) y = 2x - 5

Step-by-step 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.
