Question

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)

Answer 1

Your answer is D. (4,3)

Answer 2

D(4,3)

Step-by-step explanation

The endpoints of AB have the coordinates A(9, 8) and B(-1, -2).

To calculate the coordinates of the midpoint of AB, we use the midpoint formula,

`( (x_1+x_2)/(2),(y_1+y_2)/(2) )`

We substitute the coordinates of the endpoints into the formula to get,

`( (9+ - 1)/(2),(8+ - 2)/(2) )`

`( (8)/(2),(6)/(2) )`

We simplify further to obtain,

`( 4,3)`
