Question

if the trapezoid is reflected across the x-axis, what are the coordinates of B? A. (-9, -5) B. (-9,5) C. (-5,9) D. (5,-9)

Answer 1

B'(5,-9)

Explanation:

When reflecting across the x-axis, the "x" coordinate stays the same, and the "y" coordinate just becomes the opposite. So, the opposite of 9 is -9!

Therefore, B' is (5,-9), or "D"

Hope this helps!
