Question

Give coordinates X(3,-4) and Y(-3,-4), midpoint D of XY is?

Answer 1

Answer:

$\large\boxed{D.\ D(0,\ -4)}$

Step-by-step explanation:

The formula of a midpoint of the segment"

$\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)$

We have the points X(3, -4) and Y(-3 -4).

Substitute:

$x=\dfrac{3+(-3)}{2}=\dfrac{0}{2}=0\\\\y=\dfrac{-4+(-4)}{2}=\dfrac{-8}{2}=-4$
