Question

What are the coordinates of the midpoint of AB¯¯¯¯¯ where A(−7, 2) and B(5, −9)?

(−2.5, −1)

(−6, −5.5)

(−1, −3.5)

(1, −9)

Answer 1

Your answer would be C,(−1, −3.5).

HOPE THIS HELPS! ^_^

Answer 2

`(-1,-3.5)`

Explanation:

Let

M-------> the midpoint of AB

Step 1

Find the x-coordinate of the midpoint AB

`Mx=(x1+x2)/(2)`

we have

`A(-7,2), B(5,-9)`

substitute

`Mx=(-7+5)/(2)=-1`

Step 2

Find the y-coordinate of the midpoint AB

`My=(y1+y2)/(2)`

we have

`A(-7,2), B(5,-9)`

substitute

`My=(2-9)/(2)=-3.5`

therefore

the coordinates of the point M are
`(-1,-3.5)`
