Find the equation of the plane through the point 2 i ^ + j ^ - k ^ and passing through the line of intersection of the planes r → · i ^ + 3 j ^ - k ^ = 0 and r → · j ^ + 2 k ^ = 0 . Share with your friends Share 0 Global Expert answered this The equation of the plane passing through the line of intersection of the given planes isr→. i^+3 j^-k^+λ r→. j^+2 k^=0 r→. i^+3+λ j^+-1+2λk^=0... 1This passes through 2 i^+j^-k^. So,2 i^+j^-k^ i^+3+λ j^+-1+2λk^=0⇒2+3+λ+1-2λ=0⇒λ=6Substituting this in (1), we getr→. i^+3+6 j^+-1+12k^=0⇒r→. i^+9 j^+11 k^=0 3 View Full Answer
