The line passing through the point (1,0,8) and perpendicular to the plane
A line perpendicular to the plane has the same direction as a normal vector to the plane, which is
By using the vector eqaution for the line
Thus, the vector equation of the line is
Obtain the parametric equation of line as follows.
By the parametric equation for the line through the point and parallel to the direction vector are
Thus, the parametric equation of the line is
