SUMMARY
The discussion focuses on finding the equation of a plane that contains two given lines represented in vector form. The user initially calculated the cross product of the direction vectors of the lines, resulting in the normal vector <-2,-2,0>, and derived the equation of the plane as -2(x-1)-2(y-1)=0. However, this equation simplifies to the equivalent form x+y=2, demonstrating that multiple representations exist for the same plane. The conversation emphasizes that while there are various forms to express a plane's equation, they can be equivalent.
