Question

What is the distance between `(-12,4)` and `(-10,-5)`?

Answer 1

`sqrt(85)`

Explanation:

Use pythagoras to find the distance

`distance = sqrt((-12-(-10))^2 + (4-(-5))^2)`
`distance = sqrt(2^2 + 9^2)`
`distance = sqrt(4+81)`
`distance = sqrt(85)`

I will leave it as `sqrt(85)` since this is the exact form but you can put it into a calculator and get a rounded decimal if you want.
