Answer:

Las coordenadas del punto son P(2.\overline 3, 1)

Step-by-step explanation:

Las coordenadas de los extremos de la pieza de madera son A (5, 3) y B (-3, -3)

El punto, P, en el que se agregará la muesca = 1/3 de la longitud de AB

Por tanto, las coordenadas del punto, tomando A como punto de referencia, se dan como sigue;

P (5 + (-3 - 5) × 1/3, 3 + (-3 - 3) × 1/3) = P(2.\overline 3, 1)

Las coordenadas del punto son P(2.\overline 3, 1).
