Answer:

$-1\dfrac{1}{2}$

Step-by-step explanation:

A part of the number line ranging from -2 to 2 with an arrow on both ends and tick marks every $\dfrac{1}{6}$ is shown in attached diagram.

Rules:

To add a number using number line, we have to move to the right,
To subtract the number using number line, we have to move to the left.

To subtract $\dfrac{1}{6}$ using number line, you have to move to the left one mark (because the distance between two consecutive marks is $\dfrac{1}{6}$ ), so you'll be at point $-1\dfrac{1}{2}$
