Describe the span of the given vectors geometrically and algebraically 1 u = (a) geometrically the set of all linear combinations of u, v, and w is a line through the origin with v as a direction vector. o the set of all linear combinations of u, v, and w is a plane through the origin containing u and v as direction vectors the set of all linear combinations of u, v, and w span r2. the set of all linear combinations of u, v, and w is a line through the origin with u as a direction vector. the set of all linear combinations of u, v, and w is a plane through the origin containing only u as a direction vector. (b) algebraically (enter a mathematical equation.) the general equation in terms of x, y, and z is
