Question

midpoint of (7,-9), (-9,6)​

Answer 1

Add the x values together, then divide by two. Do the exact same thing for the y values. Hope that helped.

Answer 2

The formula for midpoint is:

($\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}$)

so...

($\frac{7 + (-9)}{2}, \frac{-9 + 6}{2}$)

($\frac{-2}{2}, \frac{-3}{2}$)

so...

(-2, -1.5) <<<Midpoint

Hope this helped!
