Postulate 3: Through any three points that are not one line, exactly one plane exists. Three planes may all intersect each other at exactly one point. Translating any plane just moves the point of intersection around. Where those axis meet is considered (0, 0, 0) or the origin of the coordinate space. because both lines are described by linear homogeneous polynomials, number of intersection points is at most the product of the degree, namely $1\cdot 1=1$ but, they also cannot share a irreducible factor, othwerwise they would be identical so the claim follows.
