Option B: 3 is the right answer

Step-by-step explanation:

If y varies directly as x, it can be expressed as:

y ∝ x

$y= kx$

If the values in table are directly proportional then the value of k should be same for all pairs.

$k = \frac{y}{x}\\k = \frac{6}{2} = \frac{9}{3} = \frac{12}{4} = \frac{15}{5} = 3$

the table is directly proportional and the value of k is 3

Hence,

Option B: 3 is the right answer
