How do you determine if a particle is moving in a positive direction?

How do you determine if a particle is moving in a positive direction? Is a particle moving to the right when velocity is positive? So if the velocity is denoted by v(t), we have v(t)=s′(t)=3t2−12t+9=3(t−1)(t−3). The particle is moving to the right when the velocity is positive, and to the left when the velocity is
