Use the distance formula,
D%5E2=%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2
D%5E2=%28-9-%28-8%29%29%5E2%2B%28-13-5%2F7%29%5E2
D%5E2=%28-9%2B8%29%5E2%2B%28-91%2F7-5%2F7%29%5E2
D%5E2=%28-1%29%5E2%2B%28-96%2F7%29%5E2
D%5E2=1%2B9216%2F49
D%5E2=49%2F49%2B9216%2F49
D%5E2=9265%2F49
D=sqrt%289265%2F49%29
D=%281%2F7%29%2Asqrt%289265%29
