Why would lines segments, rays, or planes not exist if points do not exist

Points act as a reference for line segments, rays and planes. In order for one of these geometric features to exist, some form of location would have to be given. Points act as reference so that these features can be plotted.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
