Suppose $M$ is a hyperbolic Moebius transformation with fixed points at $(0, 0), (1, 0)$ which, when applied to the complex $(x_0, y_0)$, yields the result $(x_1, y_1)$.
How do I solve for $M$ given $x_0, y_0, x_1$, and $y_1$?

The transformation we are looking for is $\frac{w}{w-1}=k~\frac{z}{z-1}$ with $0
Hint: You can take your matrix representation of the Möbius transformation to be an element of $PSL(2,\mathbb{R})$, or your transformation to be $T(z)= \frac{az+b}{cz+d}$ with $ad-bc=1$. Then with the conditions $T(0)=0, T(1)=1 $ and $ T(z_0)=z_1$ you should be able to solve for $a, b , c$ and $d$.
