Two planes are given by the equations :

Q: 2x+y-3z=2

R: -x+2y-z=1

(a) Find a vector normal to the plane Q. Find an equation of the plane which is parallel to Q and passes through the point (1, 2, −1).

b) Find a vector normal to the plane R. Find a vector equation of the line that is perpendicular to the plane R and passes through the point (0, 0, −1).

(c) Find a vector equation of the line in the intersection of Q and R. 

Please help with this question... I am confused on how to approach it .. thank you
