Question

find the coordinates of A' after a reflection across the y-axis and then across the line y = -2. write your answer in the form (a, b). ​

Answer 1

(3,1)

Explanation:

When a point is reflected across the y axis, the sign of its x coordinate flips. Since point A is at (-3,-5), when it is reflected across the y axis its new position will be (3,-5). Now, point A is 3 units from the line y=-2, meaning that when it is reflected across it will be 3 units away from the other direction. (-2+(3))=1, meaning that the final coordinates of point A are (3,1). Hope this helps!
