What happens when a shape is reflected over the x-axis?
The x-coordinate changes, and the y-coordinate remains the same.
The y-coordinate changes, and the x-coordinate remains the same.
Both x and y coordinates change.
Neither x nor y coordinate changes.
Explicação
When reflecting across the x-axis, the y-coordinate is negated (changes sign), while the x-coordinate remains the same.
