Find the vector and the cartesian equations of the line that passes through the points $(3, -2, -5), (3, -2, 6).$

Question

$\begin{array}{1 1}\large\frac{x-3}{3}=\large\frac{y+2}{-2}=\large\frac{z+5}{6} \\ \large\frac{x-3}{3}=\large\frac{y+2}{-2}=\large\frac{z+5}{-5} \\ \large\frac{x-3}{0}=\large\frac{y+2}{0}=\large\frac{z+5}{11} \\\large\frac{x-3}{0}=\large\frac{y+2}{0}=\large\frac{z+5}{1} \end{array} $
