Question

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

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

Answer 1

A. 5

Explanation:

The formula of a distance between two points:

`d=√((x_2-x_1)^2+(y_2-y_1)^2)`

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

Substitute:

`d=√((-1-(-4))^2+(0-(-4))^2)=√((-1+4)^2+(0+4)^2)\\\\=√(3^2+4^2)=√(9+16)=√(25)=5`
