Planes x and y and points j, k, l, m, and n are shown. vertical plane x intersects horizontal plane y. point l is on the left half of plane y. point n is on the bottom half of plane x. point m is on the right half of plane y. point k is on the top half of plane x. point j is above and to the left of the planes. exactly how many planes contain points j, k, and n?
