Question

If R(5,6) is the midpoint of the line segment AB joining the points A(6,5) and B(4,4) then y equals (a) 5 (b) 7 (c) 12 (d) 6

Answer 1

Answer: I

s the mid-point of the line segment AB joining the points A (6, 5) and B (4, y), then y equals. ... Member since Apr 11 2014. Given points are A (6, 5) and B (4, y). Mid point of AB = R Mid point = [ ( 6 + 4) / 2 , ( 5 + y) / 2 ] = ( 5 , 6) (5 + y) / 2 = 6 5 + y = 12 y = 12 - 5 y = 7. SME

Step-by-step explanation:

Answer 2

Answer:

Since R(5, 6) is the midpoint of the line segment AB joining the points A(6, 5) and B(4, y), therefore

⇒5+y/2=6

⇒5+y=12

⇒y=12−5=7

⇒5+y2=6

⇒5+y=12

⇒y=12-5=7

Hence, the correct option is (b).
