You can put this solution on YOUR website!
Let P and Q 2 points/ P=(a,b) Q=(c,d)
then
Midpoint is ((a+c)/(2),(b+d)/(2))
and distance between P and Q = d%28P%2CQ%29=sqrt%28%28c-a%29%5E2%2B%28d-b%29%5E2%29
if P=(-2,4)and Q= (-3+3* sqrt(3),7)
Midpoint is ((-5+3* sqrt(3))/2,11/2)}}}
d%28P%2CQ%29=sqrt%28+%283%2Asqrt%283%29-1%29%5E2%2B3%5E2%29=
sqrt%2827%2B1-6%2Asqrt%283%29%2B9%29=sqrt%2837-6%2Asqrt%283%29%29
