Question

the coordinates of the midpoint of the line segment joining the points (2 a+2,3) and (4, 2 b+1) are (2 a, 2 b). find the values of a and b.

Answer 1

this is ur answer,,,,

Answer 2

Let mid point be c(x,y)

Then x=(x1+x2)/2

But x=2a

2a=(2a+4)/2

4a=2a+4

2a=4

a=4/2

a=2

Similarly

2b=(3+2b+1)/2

4b=2b+4

4b-2b=4

2b=4

b=2

a=2&b=2
