Someone help me out. I dont know how to do this

Step-by-step explanation:

Read the coordinates of the points:

A(-1, 0) → A'(-1, 0)

B(0, 2) → B'(0, -2)

C(3, 2) → C'(3, -2)

D(4, 0) → D'(4, 0)

(x, y) → (x, -y)

Check:

A → A': (-1, 0) → (-1, -0) = (-1, 0)    CORRECT

B → B': (0, 2) → (0, -2)      CORRECT

C → C': (3, 2) → (3, -2)        CORRECT

D → D': (4, 0) → (4, -0) = (4, 0)     CORRECT

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
