**intersections**is thus equal to the order of the resultant equation in x (or y). - The notion of imaginary
**intersections**, thus presenting itself, through algebra, in geometry, must be accepted in geometry - and it in fact plays an all-important part in modern geometry. - The theorem of the m
**intersections**has been stated in regard to an arbitrary line; in fact, for particular lines the resultant equation may be or appear to be of an order less than m; for instance, taking m= 2, if the hyperbola xy - 1= o be cut by the line y=0, the resultant equation in x is Ox- 1 = o, and there is apparently only the intersection (x 110, y =0); but the theorem is, in fact, true for every line whatever: a curve of the order in meets every line whatever in precisely m points. - We have, in the case just referred to, to take account of a point at infinity on the line y=0; the two

**intersections**of the given circles. - The
**intersections**which lie on the radical axis are two out of the four**intersections**of the two circles. - The question as to the remaining two

**intersections**," and " a plane curve is said to be of the mth class when from any point of its plane there can be drawn to it m real or ideal tangents." - The points of contact are found as the
**intersections**of the curve u= o by a curve depending on the position of the arbitrary point, and called the " first polar " of this point; the order of the first polar is = m - r, and the number of**intersections**is thus =m(m - I).
