In a hexagonal binning plot, the intensity $I$ of a cell is defined as $I = \frac{n}{A}$, where $n$ is the count of points and $A$ is the area of the hexagon with side length $s$. If $A = \frac{3\sqrt{3}}{2}s^2$, and we perform a coordinate transformation where all points $x_i$ are scaled by a factor $k$, what is the relationship between the original intensity $I$ and the new intensity $I'$ given the same number of points $n$?
