Given a system of the form m1x1 + x2 = b1 m2x1 + x2 = b2 where m1, m2, b1, and b2 are constants, (a) Show that the system will have a unique solution if m1 _= m2. (b) Show that if m1 = m2, then the system will be consistent only if b1 = b2. (c) Give a geometric interpretation of parts (a) and (b). 1
