Question

Find the distance between A(−3,8)

and B(−1,4).
Round to the nearest tenth, if necessary.

Answer 1

4.50

Explanation:

d = distance between points

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

`d=\sqrt{(-1 - (-3))^2 + ( 4-8)^2)`

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

`d=\sqrt{(4+16)`

`d=\sqrt{ 20`

= 4.47 ~ 4.50
