1.	2. If P(-1, 1) is the middle point of the line segment joining A-3, b) and B(1, b+ 4) then the valueof b is(a) 1(b) - 1(c) 2(d)0
Answer» Step-by-step explanation: MIDPOINT formula :- P(y)=(y1+y2)/2 1=(b+b+4)/2 2=(2b+4) [Cross multiplying] 2-4=2b -2=2b -1=b (b) is the correct answer Please MARK BRAINLIEST

2. If P(-1, 1) is the middle point of the line segment joining A-3, b) and B(1, b+ 4) then the valueof b is(a) 1(b) - 1(c) 2(d)0

Answer»

Step-by-step explanation:

MIDPOINT formula :-

P(y)=(y1+y2)/2

1=(b+b+4)/2

2=(2b+4) [Cross multiplying]

2-4=2b

-2=2b

-1=b

(b) is the correct answer
