Answer:
(-2,3)
Step-by-step explanation:
When you reflect a point over the x axis, the y value is changed to the opposite value (positive)
So (2,-3) reflected across the x axis is (2,3)
Next, we need to reflect this across the y axis
When you reflect a point over the y axis, the x value is changed to the opposite value (negative)
(2,3) reflected across the y axis is (-2,3)
