Object moving towards or away from "origin"

Homework Statement

I just want to confirm that I got this right:

Given a s(t) relation of an object.
The object moves along a straight line.
At some time t, s(t) will tell me if the object is to the left or to the right of the origin.

If s(t) is +:
if if v(t) is +, then it is moving away from the origin.
if v(t) is -, then it is moving back towards the origin.

If s(t) is -:
if v(t) is -, it is moving away.
if v(t) is +, it is moving towards.
