Describe the path of the particle

\textbf{r} = \textbf{i} + t\textbf{j}

Answer is line x = 1 in the xy-plane.

I can find velocity, speed and acceleration but I have absolutely no clue how to describe the path of the particle.

Thanks in advance.
 
The vector function is r(t)=i+tj\displaystyle \vec{r(t)}= \vec{i}+ t\vec{j}. In an x, y coordinate system, any vector is of the form "xi+yj\displaystyle x\vec{i}+ y\vec{j}" so that vector function is the same as the parametric equations x= 1, y= t or (1, t). y can be anything but, for all y, x= 1. The path is the vertical line x= 1.
