where did you get this information? Because those springs are both progressive rate.

How could you tell either way? Just from the looks.

The coils aren't one diameter. A linear spring will always have a consistent diameter and coil spacing. Unless the spring material or thickness changed.

Those springs do not have that. You can achieve close to linear rates under normal compression if the uncompressed coils are equal diameter and spaced.
