Question

find tje distance between the points (-10, 10) and (-4, 2).

Answer 1

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the points (-10, 10) and (-4, 2). Substitute:

$d=\sqrt{(-4-(-10))^2+(2-10)^2}=\sqrt{6^2+(-8)^2}=\sqrt{26+64}=\sqrt{100}=10$

Answer: d = 10
