Question

What is the distance between `(-8,67)` and `(-1,53)`?

Answer 1

`7*sqrt(5)~~15.65=d`

Explanation:

The distance of two points can be calculated with pythagoras.

`(x_2-x_1)^2+(y_2-y_1)^2=d^2`
`p_1(-8,67)`
`p_2(-1,53)`
`(-1-(-8))^2+(53-67)^2=d^2`
`7^2+(-14)^2=d^2|sqrt()`
`sqrt(49+196)=d`
`sqrt(245)=d`
`7*sqrt(5)~~15.65=d`
