The question asks: Find the equation of the plane that passes throug the points (1,2,3), (3,-1,3), and (5,0,7). (Hint: Recall that the general equation of a plane is ax + by +cz =d.)

You could make 2 vectors with those three points then find the normal by taking the cross product of those two vectors then plug them into the general equation with xo being the ___ (one point that makes them both vectors - what's the word?)

But say you had no previous knowledge of vector geometry, how would one going about doing this problem?
