Question

# If the lines and are concurrent then λ

- 0
- 1
- -1
- 2

Hint:

### The line should satisfy the point of intersection of the pair of straight lines.

## The correct answer is: 2

### Given That:

If the lines and are concurrent then λ

>>> The point of intersection of pair of straight lines becomes:

p(x, y) =

>>> Therefore, the point of intersection becomes:

p(x, y) = (,)

>>> Therefore, it should satisfy the given line :

= 2.

>>> Therefore, the value of is 2.

>>> The value of is 2.
