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%283-8%29%5E2%2B%287-7%29%5E2%29 Plug in x%5B1%5D=3, x%5B2%5D=8, y%5B1%5D=7, and y%5B2%5D=7.


d=sqrt%28%28-5%29%5E2%2B%287-7%29%5E2%29 Subtract 8 from 3 to get -5.


d=sqrt%28%28-5%29%5E2%2B%280%29%5E2%29 Subtract 7 from 7 to get 0.


d=sqrt%2825%2B%280%29%5E2%29 Square -5 to get 25.


d=sqrt%2825%2B0%29 Square 0 to get 0.


d=sqrt%2825%29 Add 25 to 0 to get 25.


d=5 Take the square root of 25 to get 5.


So our answer is d=5


So the distance between the two points is 5 units.
