Made into an equation

i believe the answer is d.

hope it you! : d

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)

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
