Step-by-step explanation: To reflect a point across the x-axis all we need to do is to keep the x-coordinate and get the inverse of the y coordinate (if it is positive the reflection will be negative but if it is negative the reflection will be positive). Once our point has the coordinates (9,3) the reflection across the x-axis will have the coordinates (9,-3)
Final answer: So the reflection of point A (IN BLUE) is represented below IN RED
