Calculate the coordinates of the point where the line

meets the plane x = -1.

A second line passes through

the points B and C with respective coordinates (3,-2, 1) and (2,1, 4). Find the Cartesian parametric equations of

this line and show that the two lines intersect. Calculate

the coordinates of the point of intersection.
