Question 197100: The midpoint of a line segment from A(2,7) to B(h,k) is M(–3,1).
DETERMINE:

a) h =
b) k =
Let A(x1,y1) and B(x2,y2) be two points
midpoint of line AB is given by %28%28x1%2Bx2%29%2F2%29,%28%28y1%2By2%29%2F2%29
So %28h%2B2%29%2F2=-3 -------(1)
%28k%2B7%29%2F2=1 ---------(2)
From (1), h%2B2=-6
h=-8
From (2), k%2B7=2
k=-5
