We may look upon Plane Co-ordinate Geometry as having points and lines for its fundamental elements ; in relations 

 of which geometrical theorems are going to be expressed. Thus the equation y = mx + c may be looked upon as a line of 

 co-ordinates (m, c). It is this view that we shall adopt.' Preface.
