M(6, 6) is the midpoint of rs. the coordinates of s are (8, 9). what are the coordinates of r?

coordinates of R ( 4 ,3) .

Step-by-step explanation:

Given :M(6, 6) is the midpoint of RS. The coordinates of S are (8, 9).

To find :What are the coordinates of R.

Solution : We have given Mid point ( 6,6)

End  points R( x , y) and S (8 , 9) .

.

Here , .

The plug the values in given formula.

.

For ,  6 = .

On multiplying both sides by 2

12 = x +8

On subtracting both sides by 8

x = 4 .

For , 6 = .

On multiplying both sides by 2

12 = y + 9

On subtracting both sides by 9

y= 3.

Then coordinates of R ( 4 ,3) .

Therefore, coordinates of R ( 4 ,3) .

what? that isnt a question
