Question

the line ab has a mid point (2,5) a has coordinates of (1,7) find the coordinates of b

Answer 1

Answer:

b(3,3) is the answer to the question

Answer 2

Mid point = P(2,5)

A(x1 , y1) = (1 , 7)

B(x2 , y2)

2 = (x1+x2)/2

=> 2*2 = 1 + x2

=> 4-1 = x2

=> x2 = 3

Similarly,

5 = (y1 + y2)/2

=> 10 = 7 + y2

=> y2 = 10 - 7

=> y2 = 3

.•. point B is B(3,3)
