Question

if (3,4) is mid point of the line sagment whose one end is (7,-2 ) then find the coordinates of the other end point​

Answer 1

Mid point of two points (x

1

,y

1

) and (x

2

,y

2

) is calculated by the formula (

2

x

1

+x

2

,

2

y

1

+y

2

)

Let the other point be (x,y)

So, =(

2

3+x

,

2

5+y

)=(5,8)

=>

2

3+x

=5 and

2

5+y

=8

=>x=7,y=11

So, the second end point is (7,11)
