What is the image of left parenthesis, minus, 3, comma, minus, 9, right parenthesis(−3,−9) after a reflection over the x-axis?

To reflect a point over the x-axis, you need to change the sign of the y-coordinate while keeping the x-coordinate the same.

The given point is \((-3, -9)\).

• The x-coordinate is \(-3\), which remains the same.
• The y-coordinate is \(-9\). When reflecting over the x-axis, this becomes \(9\).

Therefore, the image of the point \((-3, -9)\) after reflection over the x-axis is \((-3, 9)\).
