Let \(A(1,\ 2)\), \(B(5,\ 4)\), and \(C(9,\ 6)\).
  1. Calculate the vector \(\Vect{AB}\).
    \(\Vect{AB} = \begin{pmatrix} \input{124616}{}{3em}{2em}{}{} \\ \input{224616}{}{3em}{2em}{}{} \end{pmatrix}\)
  2. Calculate the vector \(\Vect{AC}\).
    \(\Vect{AC} = \begin{pmatrix} \input{324616}{}{3em}{2em}{}{} \\ \input{424616}{}{3em}{2em}{}{} \end{pmatrix}\)
  3. Calculate the determinant \(\det(\Vect{AB},\,\Vect{AC})\).
    \(\det(\Vect{AB},\,\Vect{AC}) = \)
  4. Are the points \(A\), \(B\), and \(C\) aligned?
