Through:(-1,2) slope=-1

y = -x + 1

Step-by-step explanation:

y - y1 = m (x - x1)

y-2 = -1 (x - (-1))

y -2 = -x-1

y = - x -1 + 2

y = -x + 1

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)
