Question

Rectangle ABCD is reflected on a coordinate plane over the x axis to create imagine A’ B’ C’ D’. Which property changed when creating the image A’ B’ C’ D’?

Answer 1

see the explanation

Explanation:

we know that

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite

so

The rule of the reflection of a point across the x-axis is

(x,y) ----> (x,-y)

therefore

When creating image A' B' C' D', the x-coordinates of the image remain the same as the x-coordinates of the pre-image and the y-coordinates of the image are the opposite of the y-coordinates of the pre-image.
