Add the x values together, then divide by two. Do the exact same thing for the y values. Hope that helped.
The formula for midpoint is:
([tex]\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}[/tex])
so...
([tex]\frac{7 + (-9)}{2}, \frac{-9 + 6}{2}[/tex])
([tex]\frac{-2}{2}, \frac{-3}{2}[/tex])
so...
(-2, -1.5) <<<Midpoint
Hope this helped!
