Question

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

A. D(-4,0)
B. D(-3,4)
C. D(3,-4)
D. D(0,-4)

Answer 1

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

Explanation:

The formula of a midpoint of the segment"

`\left((x_1+x_2)/(2);\ (y_1+y_2)/(2)\right)`

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

Substitute:

`x=(3+(-3))/(2)=(0)/(2)=0\\\\y=(-4+(-4))/(2)=(-8)/(2)=-4`
