Question

Point S is the midpoint of RT the coordinates of point R and point T are listed below R(-11,-12) T(-7,-4) what are the coordinates of point S

Answer 1

Answer:

S (- 9, - 8 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( $\frac{x_{1}+x_{2} }{2}$ , $\frac{y_{1}+y_{2} }{2}$ )

here the endpoints are R (- 11, - 12 ) and T (- 7, - 4 ) , then

midpoint = ( $\frac{-11-7}{2}$ , $\frac{-12-4}{2}$ ) = ( $\frac{-18}{2}$ , $\frac{-16}{2}$ ) = (- 9, - 8 )
