1. Reemplace \( x \) y \( y \) en la ecuación del plano \( 3x + 4y - 5 = 0 \) con las coordenadas del punto \( P(12, 6) \):
d = \frac{|3(12) + 4(6) - 5|}{\sqrt{3^2 + 4^2}}
2. Simplifique la expresión para numerador:
- Calcule \( 3(12) + 4(6) - 5 \):
36 + 24 - 5 = 55
3. Simplifique la expresión para the denominador:
- Calcule \( \sqrt{3^2 + 4^2} \):
\sqrt{9 + 16} = \sqrt{25} = 5
4. Calcule el resultado final:
\frac{|55|}{5} = \frac{55}{5} = 11
5. La distancia desde el punto \( P \) a la línea es \( d = 11 \) metros
