Consider the plane?: -x + 2y - 5z = 0 and the lines:x = 4m,L? : y = -5m,z = 2mx = 4 + 3t,L2: y = 3,z=-tPart(a) [6 points] A line L is perpendicular to the plane ? and passes through the intersection point of ? and L2. Find the parametric equations of the line L.Part (b) [6 points] Find the point-normal equation of a plane ?* that contains the line L? and is also perpendicular to ?.
