My people used to put it as y = mx + b. A lot of them where physicists tho. This y = mx + the speed of light business is interesting

A scalar is a vector in a one-dimensional space, like a set of train tracks.

If scalars had a scalarity dimension, what would you get if you multiplied the scalarity unit vector by a geometric unit vector?

Similar situation here, but I was taught with context dependence. Refer to it as a vector if the direction was relevant and speed if the absolute value was. the scalar just encorprates the i and j part of the vector in the slope intercept form
