which is the projection of L, onto the xy-plane. (In other words,
the points on L₂ are directly beneath, or above, the points
on L₁.)
(a) Find the coordinates of the point P on the line L₁.
(b) Locate on the diagram the points A, B, and C, where
the line L₁ intersects the xy-plane, the yz-plane, and the
xz-plane, respectively.
