Coordinate systems and figures scale

Hi! I am studying for the GRE and noticed that, using prepswift, in question 16 of tickbox quiz 7, it is said that “coordinate systems, such as xy-planes and number lines, are drawn to scale.”. In other questions in the geometry part, however, this does not seem to apply. So, does to be sure: am I on the right track here (coordinate systems are drawn to scale, while geometric figures aren’t)?

Yes. And number lines are also drawn to scale.
