The coordinates of R are![(x_1,y_1)=(4,5)](/tpl/images/0282/3685/df298.png)
Step-by-step explanation:
Given : M(5, 7) is the midpoint of RS. The coordinates of S are (6, 9).
To find : What are the coordinates of R?
Solution :
We have given,
A line RS which has a mid point M.
Let, the coordinates of R be![(x_1,y_1)](/tpl/images/0282/3685/c8033.png)
The coordinates of S are![(x_2,y_2)=(6, 9)](/tpl/images/0282/3685/d5461.png)
The coordinates of M are![(x_3,y_3)=(5,7)](/tpl/images/0282/3685/fab93.png)
Applying mid-point formula,
Solve separately,
x- coordinate is
y- coordinate is
So, The coordinates of R are![(x_1,y_1)=(4,5)](/tpl/images/0282/3685/df298.png)
