Question

If P( -1, 1 ) Is the midpoint of the line segment joining A(-3, b ) B( 1, b+4 ) then the value of 'b' is :____

Answer 1

Step-by-step explanation:

since; the co-ordinate of mid point of a line is (x1+x2)/2,(y1+y2)/2

and (x1,y1) and (x2,y2) are co-ordinates of A and B respectively

So, by using the formula we can find out value of b.
