Given two lines y=k1 * x + b1 ; y = k2 * x + b2.
Find the coordinates of the intersection point.
(The intersection point P(Xp,Yp) belongs to both lines, that is, it is a solution to this system of equations.)
How to solve this? I'm not good with geometry) Thank you in
advance)

And as I understand it, when k1 and k2 are equal, the lines are parallel.
Mutual arrangement of several straight lines on a plane

Well, you are completely lazy.

X can be found from the equality - k1 * x + b1 = k2 * x + b2

Maybe someone will be interested, Delphi project that releases an algorithm for finding the point of intersection of two lines: www.mathros.net.ua/znahodzhennja-tochky-peretynu-d...
