M(8, 7) is the midpoint of rs. the coordinates of s are (9, 5). what are the coordinates of r?
a)(10, 3)
b)(8.5, 6)
c)(16, 14)
d)(7, 9)

Answer with Step-by-step explanation:

If the mid point of (x1,y1) and (x2,y2) is (a,b) then,

Here, (x1,y1)=(9,5) and (a,b)=(8,7) we have to find (x2,y2)

⇒16=9+x2 and 14=5+y2

⇒x2=16-9 and y2=14-5

⇒ x2=7 and y2=9

Hence, The coordinate of R is:

D) (7, 9)
