b = - 1 If P (-1,1) is the midpoint of the line segment joining A(-3,b) and B (1,b+4)
Step-by-step explanation:
P (-1,1) is the midpoint of the line segment joining A(-3,b) and B (1,b+4)
Mid point = ( - 3 + 1) /2 , ( b + b + 4)/2
=> Mid point = (-2)/2 , ( 2b + 4)/2
=> Mid point = - 1 , b + 2
Mid point is P (-1 , 1)
- 1 = - 1 &
1 = b + 2
=> b = - 1
