comment Geometric Meaning behind the algorithm (slope of the line + ray casting)
I'm really not being able to visualize "the x-coordinate of the intersection of the horizontal line going thru $testy$ and the edge". How can we be sure that it is a straight line (no slope) since with started with a comparison between the slope coefficients...

stripping the fluffly the question was "When solving problem X by heart, how does the mind reaches the solution very fast? by 'running' an algorithm or 'accessing' a table".
