Given four XY points. Let’s name them A,B, C,D, E, F, and G, H, where A,C,E and G are x values and the other are y values.
Two points, A,B to C,D makes one line and D,E and F,G makes another line.
First part, Do the intersect? (Yes or No)
If Yes, then what is the X,Y point where they do intersect?
What math computation gives the answers?
