Midpoint
x = (x1 + x2)/2
y = (y1 + y2)/2
19)
x = (x1 + x2)/2 = (5 + 4 )/2 = 4.5
y = y = (y1 + y2)/2 = (-6 + 3)/ 2 = -3/2= -1.5
Answer: Midpoint (4.5, -1.5)
20)
x = (x1 + x2)/2 = (-3 -2 )/2 = -2.5
y = y = (y1 + y2)/2 = (7 + 5)/ 2 = 6
Answer: Midpoint (-2.5, 6)
21)
x = (x1 + x2)/2 = (-2 + 8 )/2 = 3
y = y = (y1 + y2)/2 = (9 + 0)/ 2 = 4.5
Answer: Midpoint (3, 4.5)
22)
x = (x1 + x2)/2 = (-4 - 13/2 )/2 = -5.25
y = y = (y1 + y2)/2 = (1 - 6 )/ 2 = -2.5
Answer: Midpoint (-5.25, -2.5)
