Question

Find the distance between the points (-2, -4) and (-6, -8). Round your answer to to the nearest tenth.

Answer 1

Answer:

d=5.7

Step-by-step explanation:

$d=\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }$

$d=\sqrt{-6(-2)^{2}+(-8-(-4)^{2} }$

$d=\sqrt{(-6+2){^{2}+(-8+4)^{2} } }$

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

d=$\sqrt{16+16}$

d=$\sqrt{32}$

d=5.656 =5.7
