Question

If $O(0,0)$ and $P(-8,0)$ then co-ordinates of its midpoint are________.

• A. $(-4,0)$
• B. $(4,0)$
• C. $(0,-4)$
• D. $(0,0)$

Answer 1

The correct option is A $(-4,0)$

$O(0,0)$ and $P(-8,0)$ are given points.

The coordinates of the midpoint of

$\overline{OP}=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

$=(\frac{0-8}{2},\frac{0-0}{2})$

$=(-4,0)$
