Question

If the figure below were to be reflected across the x axis, what would be the coordinates for point D?

Reflection across the X-axis


D’ = ( , )

Answer 1

If the unit for the axes is 1, point D' is on coordinate (-3, -2).

Explanation:

To find coordinates' values when reflecting over the x-axis, multiply the y value of the original point by -1.

D (-3, 2) ---> D' (-3, -2)
