Points A (0,1,3), B (1,2,4), C (1,2,0) D (3,4,5) are given. Which of these points lie in the YZ plane.

If a point lies on a certain axis, then all other coordinates are equal to 0. For example, if a point lies on the X axis, then all coordinates, except x, are equal to 0.

If a point lies on a certain plane, then only the coordinates belonging to this plane differ from zero. If we need a point lying on the YZ plane, then the coordinates of this point look like this: (0; y; z). Among the given points, only point A satisfies this condition.

Answer: point A (0; 1; 3) belongs to the YZ plane.
