Answer:
A (5, 7) and B (-3, -1) ~ midpoint: (1,3)
C (3, -5) and D (-9, -3) ~ midpoint: (-3, -4)
N (-3, -4) and P (0, -1) ~ midpoint: (-3/2, -5/2)
E (-2, -5) and F (-4, -7) ~ midpoint: (-3, -6)
Explanation:
Midpoint Formula: [ (x1+x2)/2 , (y1+y2)/2 ] where (x1, y1) is a coordinate point and (x2, y2) is a coordinate point.
A (5, 7) and B (-3, -1)
x-coordinate for midpoint:
x= (5+ -3)/2
x= (2)/2
x= 1
y-coordinate for midpoint:
y= (7+ -1)/2
y= (6)/2
y= 3
C (3, -5) and D (-9, -3)
x-coordinate for midpoint:
x= (3+ -9)/2
x= (-6)/2
x= -3
y-coordinate for midpoint:
y= (-5 + -3)/2
y= (-8)/2
y= -4
N (-3, -4) and P (0, -1)
x-coordinate for midpoint:
x= (-3 + 0)/2
x= (-3)/2
x= -3/2
y-coordinate for midpoint:
y= (-4 + -1)/2
y= (-5)/2
y= -5/2
E (-2, -5) and F (-4, -7)
x-coordinate for midpoint:
x= (-2 + -4)/2
x= (-6)/2
x= -3
y-coordinate for midpoint:
y= (-5 + -7)/2
y= (-12)/2
y= -6
