PLZ HELP NNOOOOOOOWW!! 15 points!!

The midpoint of the line having the endpoints (x_1,y_1) and (x_2,y_2) is (\frac{x_{1}+_x_{2}}{2}, \frac{y_{1}+_y_{2}}{2})
basically average them


so given that the line has the endpoints of (-3,7) and (9,-2)
x₁=-3
y₁=7
x₂=9
y₂=-2

so the midpoint can be found by doing
(\frac{-3+9}{2}, \frac{7+(-2)}{2})=
(\frac{6}{2}, \frac{7-2}{2})=
(3, \frac{5}{2})

the midpoint is (3,\frac{5}{2})
