Determine whether two lines $p$ and $q$ are identical, parallel, intersecting or skew. \[\begin{aligned} p\colon x & = 1 + t, & & \\y & = 2 - t, & & \\z & = 1 - t;\ t\in \mathbb{R} & & \end{aligned}\] \[\begin{aligned} q\colon x & = 2s, & & \\y & = -1, & & \\z & = 2 - 2s;\ s\in \mathbb{R} & & \end{aligned}\]
intersecting lines
skew lines
identical lines
parallel lines, not identical
