The midpoint of AB where [tex]A(x_A;\ y_A)[/tex] and [tex]B(x_B;\ y_B)[/tex]

[tex]\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)[/tex]

[tex]A(-5;\ 13);\ B(-9;\ 21)[/tex]

The midpoint of AB: [tex]\left(\dfrac{-5+(-9)}{2};\ \dfrac{13+21}{2}\right)=\left(\dfrac{-14}{2};\ \dfrac{34}{2}\right)=(-7;\ 17)[/tex]

Answer: A. (-7, 17)
