8. find the midpoint
of the base xy in axyz.

Coordinates of the midpoint...(2;1/2)

Step-by-step explanation:

Coordinates of X(5;2) and of Y(-1;-1)

Midpoint = [ (add x coordinates of the two points)÷ 2 ; (add y coordinates of the two points) ÷ 2 ]

Mid point = [(5-1)/2 ; (2-1)/2]

Midpoint = [ 4/2 ; 1/2 ]

;Midpoint.coordinates = (2;1/2)
