Explanation
the midpoint, As the word sounds, "midpoint" means "the point in the middle"
the midpoint is given by:
[tex]\begin{gathered} m_{AB}=(\frac{x_1+x_2}{2},\frac{y_1+y_2_{}}{2}) \\ where\text{ } \\ A(x_1,y_1)andB(x_2,y_2)\text{ are the endpoints} \end{gathered}[/tex]the
Step 1
let
[tex]\begin{gathered} A=(5,3) \\ B=(1,9) \end{gathered}[/tex]now, replace in the formula
[tex]\begin{gathered} m_{AB}=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ m_{AB}=(\frac{5+1}{2},\frac{3+9}{2}) \\ m_{AB}=(\frac{6}{2},\frac{12}{2}) \\ m_{AB}=(3,6) \end{gathered}[/tex]therefore, the midpoint is
