1. Determine which number each tick mark represents.

The distance from $40$ to $−10$ is $50$. (Remember, you have to get from $40$ to $0$, which is $40$ units, and from $0$ to $−10$, which is $10$ more units.)

$50$ units divided into $5$ sections can be represented as:

$\frac{50}{5}\;=\;{10}$

Each tick mark represents $10$ units.
