[1] 3x1 + x - 1 = 0. (Note that this hyperplane is in fact a line, since it is 1- dimensional.) What is the signed perpendicular distance of point a = [-1, -1] from P? Let P be the hyperplane consisting of the set of points x = What is the signed perpendicular distance of the origin from P? What is the orthogonal projection of point a = [-1,-1] onto p? First coordinate: Second coordinate: for which
