Question

The cooridinates of the midpoint of the line segment joining the points $(-2,2)$ and $(1,-1)$ are

• A. $M(-1,1)$
• B. $M(1,-1)$
• C. $M(-0.5,0.5)$
• D. $M(0.5,-0.5)$

Answer 1

The correct option is C $M(-0.5,0.5)$


The cooridinates of the midpoint of the line segment joining the points $(-2,2)$ and $(1,-1)$ are simply the average of the corresponding coordinates of the two points.

Hence, $midpoint=(\frac{-2+1}{2},\frac{2-1}{2})$

$midpoint=(-0.5,0.5)$
