Question

If the lines $y = x + 5$ and $5 y + b x = 3$ are concurrent, then b equals

A

1

B

3

C

6

D

0

Answer

6

Explanation

Solution

If these lines are concurrent then the intersection point of the lines $4 x + 3 y = 1$ and $y = x + 5$ , is (–2, 3), which lies on the third line.

Hence, ⇒ $b = 6$
