M(8, 7) is the midpoint of RS. The coordinates of S are (9, 5). What are the coordinates of R? (16, 14) (10, 3) (8.5, 6) (7, 9)

Respuesta :

Answer:

Last option  [tex]R=(7,9)[/tex]  is the correct choice.

Step-by-step explanation:

The required co-ordinates are given as:

[tex]\frac{x+9}{2} = 8\quad \Rightarrow \quad x = 7\\\\\frac{y+5}{2}=7\quad \Rightarrow \quad y=9[/tex]

Best Regards!
