1. The problem is to list all points on the x-axis from $-12$ to $12$. 2. Points on the x-axis have coordinates of the form $(x,0)$ where $x$ is the x-coordinate and $0$ is the y-coordinate. 3. We need to list all integer points starting from $-12$ up to $12$ inclusive. 4. The points are: $(-12,0), (-11,0), (-10,0), \ldots, (0,0), \ldots, (10,0), (11,0), (12,0)$. 5. This is a simple enumeration of points along the x-axis with y-coordinate zero.
