When finding a basis for the Null Space of a matrix the number of free variables is equal to the number of vectors in a basis for that matrix. When finding the Null Space, ALWAYS reduce to Reduced Row Echelon Form (RREF). From There, it is just finding the solution to Ax = 0. where x and zero are vectors. The solution sets of homogeneous linear systems provide an important source of vector spaces. Let A be an m by n matrix, and consider the homogeneous system. Since A is m by n, the set of all vectors x which satisfy this equation forms a subset of R n.
