Answer» Point P (x, y) bisected line joining points A(2, - 1) and B(5, - 6) Then,x = (2 +5)/2 = 7/2y = (- 1-6)/2 = - 7/2 Point P(x, y) = (7/2, - 7/2) Now point P(7/2, - 7/2) lies on line 2x + 4y + k = 0 27/2 + 4 -7/2 + k = 0 7 - 14 + k = 0 k = 7

Answer»

Point P (x, y) bisected line joining points A(2, - 1) and B(5, - 6)

Then,x = (2 +5)/2 = 7/2y = (- 1-6)/2 = - 7/2

Point P(x, y) = (7/2, - 7/2)

Now point P(7/2, - 7/2) lies on line 2x + 4y + k = 0

2*7/2 + 4 *-7/2 + k = 0

7 - 14 + k = 0

k = 7
