Find the constant of variation k for the direct variation.
1 answer:
Answer:
The correct option is D.
Step-by-step explanation:
It is given that x is directly proportional to f(x) and constant of variation is k.
Therefore k is the slope.
Slope formula is
From the table the two points are (0,0) and (3,6).
Therefore the value of constant of variation is 2 and option D is correct.
