Question

What is the distance between the points (-4, -4) and (-1,0)?

A. 5
B. 1
C. 7
D. -9

Answer 1

Answer:

A. 5

Step-by-step explanation:

The formula of a distance between two points:

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

We have two points (-4, -4) and (-1, 0).

Substitute:

$d=\sqrt{(-1-(-4))^2+(0-(-4))^2}=\sqrt{(-1+4)^2+(0+4)^2}\\\\=\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}=5$
