Answer:
The midpoint of CD is (3, 2)
Step-by-step explanation:
The movement of x is +2 from C to D and the movement of y is 16 from C to D
2 (C's x coordinate) +2/2 (to find the movement up to the x coordinate of the midpoint) and -6 (C's y coordinate) + 16/8 (to find the movement up to the y coordinate of the midpoint)
This is 2+1 as the x coordinate and -6+8 as the y coordinate that is (3, 2)
