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)M(m1,m2)=(c1+d12,c2+d22)=(2+(2)2,9+(9)2)=(0,0)

(0,0)(0,0)

Explanation:

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

M=[1/2(2+(-2)),1/2(9+(-9)]=(0,0)M=[12(2+(2)),12(9+(9)]=(0,0)

(0, 0)(0,0)

Explanation:

Just take their averages:

For x value (2-2)/2=0222=0

For y value (9-9)/2=0992=0

Your midpoint is (0, 0)

By using the midpoint formula

Explanation:

enter image source here

(2+ -2)/22+22 , (9+ -9)/29+92

And your answer is (0,0)(0,0)
