You can put this solution on YOUR website!
Use the distance formula,(-2,-6) and (7,-3)
D%5E2=%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2
D%5E2=%28-2-7%29%5E2%2B%28-6-%28-3%29%29%5E2
D%5E2=%28-9%29%5E2%2B%28-3%29%5E2
D%5E2=81%2B9
D%5E2=90
D=sqrt%2890%29
D=3sqrt%2810%29
The answer is D. 3sqrt%2810%29
