P1(-7, 9)
P2(10, -6)
Distance between P1 and P2 in x:
dx = 10 - (-7) = 10 + 7 = 17
Half the distance in x: 17/2 = 8.5
If we add this value to the x of P1, we get the x of the middle point: -7 + 8.5 = 1.5
x of the middle point = 1.5
Distance between P1 and P2 in y:
dy = -6 - 9 = -15
Half the distance in y: -15/2 = -7.5
If we add this value to the y of P1, we get the y of the middle point: 9 + (-7.5) = 9 - 7.5 = 1.5
y of the middle point = 1.5
Answer:
Midpoint (1.5, 1.5)
