The answer is UV intersects plane P. In geometry, an intersection is a point, line, or curve joint in two or more objects (for example lines, curves, planes, and surfaces). The simplest case in Euclidean geometry is the intersection points of two distinct lines that is either one point or does not exist if lines are parallel. In the problem, the point that is produced by the pencil for writing the homework made the intersection between the pencil and the paper.
