Question

if M(4,5) is the mid point of the line segment AB and co-ordinates of A(3,4)then find co-ordinates of point B

Answer 1

..... (5,4) according to me... hope might be correct

Answer 2

The mid point of AB line is M(4,5)
A(3,4)
The ratio of M by N is 1 by 1
X=mx2+mx1 by M1+ m 2
1×x2+1×3 by 1+1
4 =X2+3 by2
8 =X2+3
5 =X2
X2=5
Y=my2+ my1 by M1+ M2
5=1×y2+1×4by 2
Y2=10-4
Y2=6
