Three planes are defined as follows: -7x+ -2y+ -7z+ 30 = 0 -6x+ -5y + -10z + 0 = 0 -10x+ 6y + -7z+ 24 = 0 Determine how these planes intersect. If they intersect in a line, let your answer be the z- coordinate of the direction vector. If they do not intersect, write "NULL". If they intersect in a plane, write "coincident". If they intersect at a point, provide the z-coordinate of the point.
