M(9, 8) is the midpoint of side RS. The coordinates of S are (10, 10). What are the coordinates of R? No nonsense answers will report and give explanation plz.

the change in x  is 1 and 2 in y respectively

the points are in order from r (x,y)         to     m (9,8)         to   s (10,10

if we take - 1 from x and 2 from y we will get r, or (8,6)
