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)
