Finding solution to image lines

[kc64]

I have used the vision system VI, IMAQ Select Line, to generate lines that overlay features on my image.  Now, I want to solve for the point that all of the lines intersect through.  Since I have two (x,y) pairs for each line from the IMAQ Select Line VI, what is the best way to find the intersecting point?

That's a basic algebra problem.  Equation of two lines.  See this thread for ideas.
