Note: is the first point and is the second point .



d=sqrt%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29 Start with the distance formula.


d=sqrt%28%2821--3%29%5E2%2B%28-32--25%29%5E2%29 Plug in x%5B1%5D=21, x%5B2%5D=-3, y%5B1%5D=-32, and y%5B2%5D=-25.


d=sqrt%28%2824%29%5E2%2B%28-32--25%29%5E2%29 Subtract -3 from 21 to get 24.


d=sqrt%28%2824%29%5E2%2B%28-7%29%5E2%29 Subtract -25 from -32 to get -7.


d=sqrt%28576%2B%28-7%29%5E2%29 Square 24 to get 576.


d=sqrt%28576%2B49%29 Square -7 to get 49.


d=sqrt%28625%29 Add 576 to 49 to get 625.


d=25 Take the square root of 625 to get 25.


So our answer is d=25


So the distance between the two points is 25 units.
