Question

If origin is the mid point of the line joining of the points A(4-6) and B(a,b) the

values of ‘a’ and ‘b’ are equal to

A. a = 4 and b = 6 B. a = -4 and b = -6

C . a = -4 and b = 6 D. a = 6 and b = 4​

Answer 1

Answer:

c is right answer

Step-by-step explanation:

because

formula of mid point is

{ (X1 +X2)/2 , (y1+y2)/2 }= (x,y)

put the value

{ (4+a)/2 , (-6+b) } = { 0,0 }

compare both side

4+a = 0 and -6+b =0

a = -4 and b = 6

is Anwer

Answer 2

a=-4and b=4
