1. Determinamos la pendiente \(m\) usando el ángulo dado:

\[

m = \tan(45^\circ) = 1

\]


2. Utilizamos la fórmula de la recta \(y = mx + b\), insertando la pendiente:

\[

y = x + b

\]


3. Insertamos el punto \(A (4, -6)\) en la ecuación para encontrar \(b\):

\[

-6 = 4 + b

\]


\[

b = -10

\]


4. Finalmente, obtenemos la ecuación de la recta:

\[

y = x - 10

\]


\[

\boxed{y = x - 10}

\]
