Question

1. use the distance formula to find pq; p (15, 3), q (6, -9)

pq = ______

Explanation:

Step1: Identificar coordenadas

$x_1 = 15$, $y_1 = 3$, $x_2 = 6$, $y_2=-9$

Step2: Aplicar fórmula de distancia

$PQ=\sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}=\sqrt{(6 - 15)^2+(-9 - 3)^2}=\sqrt{(-9)^2+(-12)^2}=\sqrt{81 + 144}=\sqrt{225}=15$

Answer:

$15$
