Question

find the coordinates of the midpoint HX giving that H(-1,3) and X(7,-1)
a. (3,1)
b. (0,4)
c. (-3,1)
d. (-4,0)

Answer 1

midpoint is : (x1 + x2) / 2 , (y1 + y2) / 2
(-1,3)....x1 = -1 and y1 = 3
(7,-1)...x2 = 7 and y2 = -1
now we sub and solve
m = (-1 + 7)/2 , (3 - 1) / 2
m = (6/2, 2/2)
m = (3,1) <===

Answer 2

D is the answer for the question
