Step-by-step explanation:

[tex]A(-1,9) \\ B(3,8) \\ midpoint \: = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} ) \\ [/tex]

[tex]x1 = - 1 \\ x2 = 3 \\ y1 = 9 \\ y2 = 8[/tex]

[tex]Midpoint = ( \frac{ - 1 + 3}{2} \: , \frac{9 + 8}{2} ) \\ Midpoint = ( \frac{2}{2} ,\: \frac{17}{2} ) \\ [/tex]

[tex]Midpoint =( 1 , \frac{17}{2} ) \\ [/tex]
