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 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 \(\mathbf{r}(t)=\mathbf{Q}\).
