Question

Find the distance between (2,7) and (-6,-2)

Answer 1

Answer:
`√(145)`

Explanation:

1. use the distance formula!

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

2. then using the distance formula with (2, 7) and (-6, -2) you get...

`distance= √(2 -(-6)^2 +(7 - (-2)^2)`

`distance= √(8^2 +9^2)`

`distance=  √(64 +81)`

`distance= √(145)`

`√(145)` is the simplest radical form
