Question

11. If the lines of the equations
kx - 3y =5 and 2x - y = 10 are
parallel, then the value of k is *
O 1
O 2
3
O 6​

Answer 1

Answer:Given two equations -

2x + 3y + 5 = 0

kx + 6y + 7 = 0

a1 = 2, a2 = k, b1 = 3, b2 = 6, c1 = 5, c2 = 7

Condition for parallel lines -

a1 / a2 = b1 / b2

Putting values

2 / k = 3 / 6

2 / k = 1 / 2

k = 2 × 2

k = 4
