ANSWER

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)
