To reflect point $H$ over the $x$-axis, follow these steps:

1. Identify the coordinates of point $H$: Let's assume point $H$ has coordinates $(x, y)$.
2. Reflect over the $x$-axis: To reflect a point over the $x$-axis, the rule is to keep the $x$-coordinate the same and multiply the $y$-coordinate by -1. So the coordinates of $H'$ (the reflection of $H$) would be $(x, -y)$.
3. Plot the new point $H'$: On the coordinate grid, plot the new point with the updated coordinates $(x, -y)$.

For example, if the point $H$ is located at $(3, 4)$, the reflection over the $x$-axis would be $H' = (3, -4)$.

If you provide the coordinates of point $H$, I can help you reflect it more precisely!

Would you like more details on reflecting points? Here are some related questions:

1. How do you reflect a point over the $y$-axis?
2. How do you reflect a point over the line $y = x$?
3. What happens when you reflect a point twice over the $x$-axis and then the $y$-axis?
4. How do reflections affect the distances between points on a grid?
5. What are the properties of reflections in coordinate geometry?

Tip: When reflecting over the $x$-axis, only the sign of the $y$-coordinate changes.
