11. S(-4,-6) and T(-7, -3); Find R.
What is the missing endpoint if S is the midpoint of RT

answer is (-7,-9)

step by step:-

S is the midpoint of RT so ,

s=

 ,    

 ,  

         ,    

R= (-7,-9)

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
