Q3 3.4

x1 Find a basis for the subspace of IR consisting of all vectors 20 2 such that -9x1+ 72 - 23 = 0. Hint: Notice that this single equation counts as a system of linear equations; find and describe the solutions. Answer: [0,0,0 ] To enter a basis into WeBWork, place the entries of each vector inside of brackets, and enter a list of these vectors, separated by commas. For instance, if your basis is 2 then you would enter [1,2,3],[1,1,1] into the
