To plot the numbers $1$, $-7$, and $12$ on a number line, follow these steps:

1. Draw a horizontal line to represent the number line.
2. Mark evenly spaced intervals on the line, with the middle point representing zero ($0$).
3. Place $1$ slightly to the right of zero.
4. Place $-7$ to the left of zero, further from $0$ than $1$.
5. Place $12$ to the far right of zero.

Here's a rough description of how it would look:

$-10 \quad -9 \quad -8 \quad -7 \quad -6 \quad -5 \quad \cdots \quad 0 \quad 1 \quad 2 \quad \cdots \quad 10 \quad 11 \quad 12$
