See below

Explanation:

The general formula for midpoint M between C and D is

M(m_1, m_2)=((c_1+d_1)/2, (c_2+d_2)/2)=((2+(-2))/2,(9+(-9))/2)= (0,0)

(0,0)

Explanation:

"the coordinates of the midpoint (M) are the average of the"
"coordinates of the endpoints"

M=[1/2(2+(-2)),1/2(9+(-9)]=(0,0)

(0, 0)

Explanation:

Just take their averages:

For x value (2-2)/2=0

For y value (9-9)/2=0

Your midpoint is (0, 0)
