Not sure if I'm in the right section, but here it goes:(adsbygoogle = window.adsbygoogle || []).push({});

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.
