**Reiny**, Monday, March 16, 2009 at 7:44pmthe closest point is surely on a line from (0,0,0) meeting the plane at right angles.

but the normal to the given plane is (1,1,-1)

so the line must have direction (1,1,-1)

it's parametric equations would be:

x = k

y = k

z = -k

sub that in to the plane to find the value of k, sub back in the parametrics

and voila, there is your point.
