Question

How do you find the coordinates of the other endpoint of a segment with the given A are (2, 3) and the coordinates of midpoint M are (4.5, 6)?

Answer 1

( 7 , 9 )

Explanation:

Let the coordinates of another end point ( say, B ) is (x,y)

Here AB is a straight line and M is mid point.So, as per mid point formula :-

`4.5 = (x+ 2) /2 and 6 = (y+3)/2`

`rArr 9 = x+2, 12 = y+3`

`rArr x = 9-2 = 7 and y= 12-3 = 9`

Hence A ( x , y ) = ( 7, 9 )
