Line Intersection and Real Number
There exists a real number $ k $ such that the equation \[\begin{pmatrix} 4 \\ -1 \end{pmatrix} + t \begin{pmatrix} 5 \\ 2 \end{pmatrix} = \begin{pmatrix} 8 \\ k \end{pmatrix} + s \begin{pmatrix} -15 \\ -6 \end{pmatrix}\]has infinitely many solutions in $ t $ and $ s $. Find $ k $.
