I need help with this question. I am not sure how to do it . Please provide detailed steps. This picture above was posted from my homework . Thank You

(4 pts) 3. Two planes are given by the equationsQ:2x+y—3z=2and R: —x+2y—z= 1.(3) Find a vector normal to the plane 0. Find an equation of the plane which is parallel to Qand 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 perpendicularto 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.
