[tex]\text{The formula of the midpoint of a segment with the end points:}\\\\A(x_A;\ y_A)\ \text{and}\ B(x_B;\ y_B)\\\\M_{AB}=\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)[/tex]
[tex]\text{We have:}\\A(-2;\ 3)\to x_A=-2;\ y_A=3\\B(1;\ 8)\to x_B=1;\ y_B=8\\\\\text{substitute:}\\\\C=\left(\dfrac{-2+1}{2};\ \dfrac{3+8}{2}\right)=\left(-\dfrac{1}{2};\ \dfrac{11}{2}\right)[/tex]
