Answer:
Step-by-step explanation:
H(1 , -7) ;L(x₂,y₂)
[tex]Midpoint =\left(\dfrac{x_{1}+x_{2}}{2}, \dfrac{y_{1}+_{2}}{2} \right)\\\\\\K(9 , 3)=\left(\dfrac{1+x_{2}}{2}, \dfrac{-7+y_{2}}{2} \right)[/tex]
Compare x and y coordinates,
[tex]\dfrac{1+x_{2}}{2}=9[/tex] ; [tex]\dfrac{-7+y_{2}}{2}=3[/tex]
1 + x₂ = 18 ; -7 + y₂ = 6
x₂ = 18 - 1 ; y₂ = 6 +7
x₂ = 17 ; y₂ = 13
L(17, 13)
