Find the mid-point of the line segment joining the points (2,-6) and (6,-4) .

Answer» Let A(2,-6) and B(6,-4) be the given points and M be the mid-point of AB .
Then , `M = ((x_(1) + x_(2))/(2) , (y_(1) + y_(2))/(2))`
`= ((2+6)/(2), (-6 +(-4))/(2)) = (4 , -5)`.
Hence , the mid point of AB is `(4,-5)`.
