Given the parametric line \(p\),
find \(m\in \mathbb{R}\) such that
the point \(C = [m;3]\)
is on the line \(p\).
\[
\begin{aligned}p\colon x& = 1 - t, &
\\y & = -3 + 2t;\ t\in \mathbb{R}
\\ \end{aligned}
\]
Given lines \(p\)
and \(q\), find
\(m\in \mathbb{R}\) such that
the lines \(p\)
and \(q\)
are parallel.
\[
p\colon x - 2y + 7 = 0,\qquad q\colon mx + 3y - 11 = 0
\]
