Question

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

Answer 1

answer is (-7,-9)

step by step:-

S is the midpoint of RT so ,

s=$\frac{R+T}{2 }$

$-4=\frac{x-7}{2}$  ,     $-6=\frac{y-3}{2}$

$-14=x-7$  ,   $-12=y-3$

$x=-7$          ,    $y=-9$

R= (-7,-9)
