WebTwo distinct lines intersect at the most at one point. To find the intersection of two lines we need the general form of the two equations, which is written as a1x +b1y +c1 = 0, and a2x +b2y +c2 = 0 a 1 x + b 1 y + c 1 = 0, and a 2 x + b 2 y + c 2 = 0. The lines will intersect only if they are non-parallel lines. http://paulbourke.net/geometry/circlesphere/ northop hotels
