Question

The midpoint of A (-4,2) and B (8,5) is

Answer 1

midpoint formula : m = (x1 + x2)/2 , (y1 + y2)/2
(-4,2)....x1 = -4 and y1 = 2
(8,5)....x2 = 8 and y2 = 5
now its just a matter of subbing..
m = (-4 + 8) / 2 , (2 + 5) / 2
m = 4/2 , 7/2
m = (2,7/2) <==

Answer 2

С(x;y)
x=(8 - (-4))/2 + (-4)=2
y=(5 - 2)/2 + 2=3,5
C(2;3,5)
