Question

If the endpoints of 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

option D is right on plato

Explanation:

Answer 2

For this case we have that by definition, the formula of the midpoint is given by:

`MP = (\frac {x_ {1} + x_ {2}} {2}, \frac {y_ {1} + y_ {2}} {2})`

We have the points are:

`(x_ {1}, y_ {1}) :( 9,8)\\(x_ {2}, y_ {2}): (- 1, -2)\\MP = (\frac {9 + (- 1)} {2}, \frac {8 + (- 2)} {2})\\MP = (\frac {9-1} {2}, \frac {8-2} {2})\\MP = (\frac {8} {2}, \frac {6} {2})\\MP = (4,3)`

Answer:

Option D
