WebRegardless of how the lines are specified, you should be able to generate two different points along the line, and then generate A, B and C. Now, lets say that you have lines, given by the equations: A 1 x + B 1 y = C 1 A 2 x + B 2 y = C 2. To find the point at which the two lines intersect, we simply need to solve the two equations for the two ...
