Question

The line ab has a mid point (2,5) a has coordinates of (1,2) find the coordinates of b

Answer 1

Mid point = P(2,5)

A(x1 , y1) = (1 , 2)

B(x2 , y2)

2 = (x1+x2)/2

=> 2*2 = 1 + x2

=> 4-1 = x2

=> x2 = 3

Similarly,

5 = (y1 + y2)/2

=> 10 = 2 + y2

=> y2 = 10 - 2

=> y2 = 8

.•. point B is B(3,8)
