I just dont get these 2 questions can someone kindly provide some explanation and solutions. Thanks

Q1: Find the vector equations (in parametric and scalar product form), of the plane which

pass through (2,-1,-2) and is parallel to 3i+j-2k and i-3k

Q2: Find the equations in scalar product form and in Cartesian form of the plane which

pass through the origin O and is perpendicular to the line r=-2k+ λ(2i-j+7k)
