When a point is reflected over the $x$-axis, the $y$-coordinate of the point changes its sign, while the $x$-coordinate remains the same.

Given the coordinates of point $J$ as $(-1, -6)$:

1. The $x$-coordinate remains $-1$.
2. The $y$-coordinate changes from $-6$ to $6$ because of the reflection over the $x$-axis.

Thus, the coordinates of the reflected point $J'$ are:

$J' = (-1, 6)$

Would you like more details on reflections or have any questions?

Here are some related questions you might explore:

1. How do you reflect a point over the $y$-axis?
2. What is the effect of reflecting a point over the line $y = x$?
3. How would you reflect a point over the origin?
4. What happens to a point's coordinates when it is reflected over the line $y = -x$?
5. How do reflections affect the distance between two points on a coordinate plane?

Tip: When reflecting over the $x$-axis, always invert the $y$-coordinate's sign while keeping the $x$-coordinate the same!
