Question

the lines l and m have vector equations.r=i+j+k+s(i-j+2k) and r=4i+6j+k+t(2i+2j+k) respectively. find the equation of the plane containing l and m,giving your answer in the form ax+by+cz=d

Answer 1

hmm, you might wanna wrap your "point" as well

Answer 2

?

Answer 3

l and m have direction vectors; and if they are to be in the same plane, they need to be parallel to a common vector, called a normal

Answer 4

cross your direction vectors for the normal

Answer 5

do you know how to cross vectors?
