Question

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?

Answer 1

Plane X

Explanation:

kindly find attached a rough sketch of the problem, that contains the drawing of the plane.

From the drawing we can see that the plane x contains points K and N.

It can be seen that point J is not located on any plane.

So the answer is only one plane which is plane x contain the point K and N.
