point a (8, -10) is reflected over the y-axis. write the coordinates of a'
(-8,10)
(8,10)
(8,-10)
(-8,10)
(-8,-10)
When a point is reflected over the y-axis, its x-coordinate changes to its opposite value.
The original point A is (8, -10), and when it is reflected over the y-axis, the x-coordinate changes to its opposite value (-8).
So, the coordinates of A' are (-8, -10).
