Coordinates of a midpoint, please help?

Question

The coordinates of the midpoint of a segment with the endpoints A( 0, 2, 4) and B (-8, 2, -6)?

Please tell me HOW you got he answer also. Thanks :)

Answer 1

The midpoint is halfway between the two points, so you take the average of each of the coordinates.

Think about it, the midpoint of the interval 2 to 4 is 3, right? That's because (2 + 4) / 2 = 3.

So (0 + -8) / 2 = -4
(2 + 2) / 2 = 2
(4 + -6) / 2 = -1

Answer 2

M=((0-8)/2 , (2+2)/2, (4-6)/2) = (-4, 2, -1)

Answer 3

The coordinates of the midpoint of a segment with the endpoints A( 0, 2, 4) and B (-8, 2, -6)?

let A(x1,y1,z1); B(x2,y2,z2)
midpoint =
{(x1+x2)/2, (y1+y2)/2, (z1+z2)/2}

plug in ....
