Q).Find the equations of the straight line that is perpendicular to the lines (2x-4)/3 = (y-6)/1 = (3 -6z)/1 and (x-2)/-1 = (3-y)/-1 = (2z-4)/-4 and which passes through the midpoint of the points (2 , 6 , 1/2) and (2 , 3 , 2)???

Q) Find the equation of the plane that passes through the point (1,-2,3) and that is parallel to the line (x-2)/3 = (y-1)/2 = (z+5)/-2?

please help me in solving these problems....
