Expert Answer:

Le the equationof the required plane be
Then the coordinates of A,B and C are A(a,0,0), B(0,b,0) and C(o,o,c) respectively.
So, the centroid of the triangle is (a/3,b/3,c/3). But, the coordinates of the centroid are (3,3,3).
Substituting the values of a,b and c in the required equation, we have
