Question

If the endpoints of AB have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of AB?

A. 5,3

B. 4,5

C. 5,5

D. 4,3

Answer 1

Answer 2

Answer:
D. (4,3)

Step-by-step explanation:
The endpoints of the line are given as (9,8) and (-1,-2)
1- Computing the x-coordinate of the midpoint:
Xmidpoint = (x1+x2) / 2 = (9+-1)/2 = 8/2 = 4
2- Computing the y-coordinate of the midpoint:
Ymidpoint = (y1+y2) / 2 = (8+-2) / 2 = 6/2 = 3

Based on the above, the midpoint is (4,3)

Hope this helps :)
