You can put this solution on YOUR website!
The formula you need to use is the following:
+sqrt%28+%28x%5B1%5D-x%5B2%5D%29%5E2+%2B+%28y%5B1%5D-y%5B2%5D%29%5E2%29%29+
Plugging in your given values this gives:
+sqrt%28+%28-2sqrt%287%29-4sqrt%287%29%29%5E2+%2B+%2810-8%29%5E2%29%29+
+sqrt%28+252+%2B+4+%29+
16 which is your answer.
Hope that helps.
