Hi
(3,4)
(1,0) M = (2,2)
(3,4)
(2,2) D/2 = sqrt(1^2 + 2^2) = sqrt(5) = 2.24
2%2A2.24%29 = 4.5 (nearest tenth), the distance between Kelvin's house and Mitch's house
D = sqrt+%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29%29
Midpoint Pt(x,y): ( %28x%5B1%5D+%2B+x%5B2%5D%29%2F2, %28y%5B1%5D+%2B+y%5B2%5D%29%2F2++%29)
