Answer:
Coordinates of P = (x1, y1) = (8, 10)
Coordinates of S = (x2, y2) = (12, -6)
R is given to be the midpoint of segment PS
The coordinates of the midpoint of a segment whose end points are (x1, y1) & (x2, y2) is ,
[(x1+x2)/2, (y1+y2)/2]
∴ Coordinates of R = [(8+12)/2, (10-6)/2] = (10, 2)
Similarly, Q is also given to be the midpoint of segment RS.
∴ Coordinates of Q
= [(10+12)/2, (2-6)/2]
=(22/2, -4/2)
= (11, -2)
