Question

Find midpoint of xy X(7,-5) and y (9,-1)

Answer 1

Answer:

(8,-3)

Step-by-step explanation:

(x1+x2/2), (y1+y2/2)

7+9/2=16/2=8           x=8

-5-1/2=-6/2=-3          y=-3

Answer 2

Answer:

(8, -3)

Step-by-step explanation:

The formula of a midpoint of AB

$A(x_A,\ y_A),\ B(x_B,\ y_B)\\\\M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)$

We have the points X(7, -5) and Y(9, -1).

Substitute:

$M_{XY}\left(\dfrac{7+9}{2};\ \dfrac{-5+(-1)}{2}\right)\\\\M_{XY}\left(\dfrac{16}{2};\ \dfrac{-6}{2}\right)\\\\M_{XY}(8,\ -3)$
