Given A(-2, 5) and B(13, -7), find the midpoint of AB.​
Dmitrij [34]

Answer:

The mid-point is (9,-9/2)

Step-by-step explanation:

You would use the mid-point formula for this

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

if you plug that in it is (\frac{13-2}{2}, \frac{-7+5}{2})

resulting in (11/2,-2/2) = (11/2,-1)
