If two line pa + b = 2 and 3a + b = 4 are parallel to each other, then what is the value of p ?

Correct Answer: 3

Explanation:

Given two lines are parallel

pa+b=2

b=-pa+2..........(1)

3a+b=4

b=-3a+4 ...........(2)

m₁ = -p

m₂= -3

The condition for the two lines to be parallel is m₁=m₂

p = 3
