Select the correct answer. if the endpoints of    have the coordinates  a(9, 8) and  b(-1, -2),  what is the midpoint of  ?   a.  (5, 3)b.  (4, 5)c.  (5, 5)d.  (4, 3)

D. (4,3)

The x coordinates of A and B are 9 and -1 in that order. Add them up to get 9+(-1) = 9-1 = 8. Then divide by two to end up with 8/2 = 4. The midpoint has an x coordinate of 4.

Repeat for the y coordinates. Add them up: 8+(-2) = 8-2 = 6. Then divide by two: 6/2 = 3. The midpoint has an y coordinate of 3.

Those two coordinates pair up to get (x,y) = (4,3) which is the midpoint of segment AB.

8121 because

130,000 divided by 16 is 8121
