Find the midpoint.
It's the average of x and y values.
x%5Bm%5D=%282%2B%28-8%29%29%2F2=-6%2F2=-3
y%5Bm%5D=%283%2B%28-5%29%29%2F2=-2%2F2=-1
Now use the distance formula,
D%5E2=%28-3-%28-4%29%29%5E2%2B%28-1-6%29%5E2
D%5E2=%281%29%5E2%2B%287%29%5E2
D%5E2=50
D=sqrt%2850%29
highlight%28D=5sqrt%282%29%29
