    Remember that to get vector equation you need any point that lies on to the line and a vector that goes in the same direction.

    You could pick point P or point Q.

    You could try\[\mathbf{r}(t)=\mathbf{P}+t(\mathbf{Q}-\mathbf{P}),\qquad0\leq t\leq1.\]Notice that if \(t=0\), then \(\mathbf{r}(t)=\mathbf{P}\), and if \(t=1\), then \(\mathbf{r}(t)=\mathbf{Q}\).

    @across Do I just plug in the values P and Q for that formula?

    so, i end up with r(t)=(2,0,0)+t(4,2,-2). Is this correct?
