Essay

Give a set of parametric equations for the line containing the points $( 2,1,1 ) \text { and } ( 4,3,2 )$
A) $\begin{array} { l } x = 1 + t \\y = - 2 + 3 t \\z = 2 + 2 t\end{array}$
B) $\begin{array} { l } x = 2 + 2 t \\y = 1 + 2 t \\z = 1 + t\end{array}$
C) $\begin{array} { l } x = 1 + t \\y = 3 + 2 t \\z = 2 + 2 t\end{array}$
D) $\begin{array} { l } x = 1 + t \\y = 2 + 3 t \\z = 2 + 2 t\end{array}$
