Find a plane containing the line {x(t)=67ty(t)=7+3tz(t)=1+8t\displaystyle {\left\lbrace\begin{array}{ccc} {x}{\left({t}\right)}&=&-{6}-{7}{t}\\{y}{\left({t}\right)}&=&{7}+{3}{t}\\{z}{\left({t}\right)}&=&-{1}+{8}{t}\end{array}\right.} and orthogonal to the plane 6x+6y+3z=8\displaystyle {6}{x}+{6}{y}+{3}{z}={8}
