Question

HURRY PLEASEEEEE The measure of segment AB with a(-4,-9) and B(4, -3) is

Answer 1

Answer: 10

Step-by-step explanation:

using $d = \sqrt{(x_{1}-x_{2} )^{2} +(y_{1}- y_{2} )^{2} }$ when $P_{1} =(x_{1} ,y_{1} )$ and $P_{2} = (x_{2}, y_{2})$

so $d = \sqrt{((-4)-4)^{2}+((-9)-(-3))^{2} }$

$d = \sqrt{(-4-4)^{2}+(-9+3)^{2} }$

$d = \sqrt{(-8)^{2}+(-6)^{2} }$

$d = \sqrt{64+36}$

$d= \sqrt{100}$

$d = 10$
