Question

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

Answer 1

(8,-3)

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

(8, -3)

Explanation:

The formula of a midpoint of AB

`A(x_A,\ y_A),\ B(x_B,\ y_B)\\\\M_(AB)\left((x_A+x_B)/(2);\ (y_A+y_B)/(2)\right)`

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

Substitute:

`M_(XY)\left((7+9)/(2);\ (-5+(-1))/(2)\right)\\\\M_(XY)\left((16)/(2);\ (-6)/(2)\right)\\\\M_(XY)(8,\ -3)`
