Question

If P(2.a) is mid point of line
segment joining the points
A(6,-5) and B(-2,11).Find a
​

Answer 1

Answer:

a = 3

Step-by-step explanation:

Let A(6,-5) = A(p,q) i.e p=6 and q=-5

B(-2,11) = B(x,y) i.e x=-2 and y=11

Mid point of A and B = P(2,a)

Mid point formula = P( (p+x)/2 , (q+y)/2 )

Therefore , a = ( q+y ) / 2

= (11+(-5))/2

= 6/2 = 3
