Geometric Solutions for 2D Intersections

Greetings,

Perhaps I use "geometric" as an incorrect synonym for "visual",
however I am looking for solutions that can be constructed using ruler/
compass and are visually apparent on paper.

The intersection of two straight, infinite lines is a 2x2 linear
system that can be solved algebraically - but is there a visual
solution?

I think the main problem is visualizing ratio's. It is not apparent
that one distance is proportionate to another - simply by observation.

I have also messed with line-circle intersection for years, but I
think there must only be an algebraic solution.

Any thoughts appreciated.
