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:

for your answer

Step-by-step explanation:

if origin is the mid point of the line joining of the point A(4-6) and By(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

this is write answer

Answer 2

Answer: option b

Step-by-step explanation:

P(0,0) = [4 + a/2 , 6 + b/2]

x = 0 = 4+a/2, y = 0 = 6+b/2

x = 0 = 4+a , y = 0 =6+b

Therefore, -4 = a & -6 = b

You can check if it's correct by using midpoint formula and using -4 & -6 in place of a & b respectively
