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

D(4,3)

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,

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

We simplify further to obtain,

yes

step-by-step explanation:

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
