Question

What are the coordinates of the pre image of B

Answer 1

It’s b (-8,-2

Explanation:

I took the quiz

Answer 2

Point B = (-8 , -2) ⇒ the second answer

Explanation:

∵ The figure ABCD is reflected across the x-axis

∴ The sign of y-coordinates of each point will change

Ex: If the point (x , y) reflected across the x-axis

its image will be (x , -y)

∵ B' = (-8 , 2)

∴ B = (-8 , -2) ⇒ the second answer
