Question

Find the distance between the pair of points. (-16, 12) and (-22, -19).

Answer 1

`d = \sqrt{(x_(2) - x_(1))^(2) + (y_(2) - y_(1))^(2)}`

`d = \sqrt{[-22 - (-16)]^(2) + (-19 - 12)^(2)}`

`d = \sqrt{(-22 + 16)^(2) + (-31)^(2)}`

`d = \sqrt{(-6)^(2) + (-31)^(2)}`

`d = √(36 + 961)`

`d = √(997)`

`d \approx 31.57`
