The endpoints C and D has nomidpoint M.
Step-by-step explanation:
step 1: The given endpoints of C and D are (-4,10) and (-4,10)
step 2: Midpoint formula = ((x1+x2)/2 , (y1+y2)/2)
step 3: Here, C(-4,10) = (x1,y1)
D(-4,10) = (x2,y2)
step 4: The midpoint represents the half distance of the line CD. Since C and D are same points, they cannot form a line. Therefore, the endpoints CD have no midpoint.
