distance between (1, 7), and (-7, 1)

Question

 HELP 

Answer 1

We have to remember the distance formula:  √(x₂-x₁)² + (y₂-y₁)²   (the square root of all of that)

And remember that our coordinates are given to us in (x, y) so then you would just take the square root of (-7-1)² +(1-7)² and that would be your distance!

Answer 2

distance between (1,7) and (-7,1)

use the distance formula

√[(-7-1)²+(1-7)²]

√[(-8)²+(-6)²]

√(64+36)

√100=10 units
