Find the parametric equation of the line through A(1,2,1) and B(-1,3,2). help pleaseeee it involves vectors

If points \(\displaystyle P:<p_1,p_2,p_3>~\&~Q:<q_1,q_2,q_3>\) then the line is \(\displaystyle \overleftrightarrow {PQ}\) is
\(\displaystyle \left\{ {\begin{array}{*{20}c} {x = p_1 + t(q_1 - p_1 )} \\ {y = p_2 + t(q_2 - p_2 )} \\ {z = p_3 + t(q_3 - p_3 )} \\ \end{array} } \right.\)
