Not sure if I'm in the right section, but here it goes: 1. The problem statement, all variables and given/known data Find the equation of the plane which contains: i) the intersection of -3x-2y-2z=9 and -2x-3y-2z=9 ii) the point (-2,-3,-4) Write the equation in the form Ax+By+Cz=D 2. Relevant equations Cross Product, perhaps triple product? 3. The attempt at a solution I've solved for the direction vector where the two planes intersect: This vector I solved for was [-2,-2,5] At this point I'm stuck.... I don't know what my next move is. If anyone can help that would be greatly appreciated.
