Question

show what you know
here are the coordinates of the pre - image and image of triangle cat.
which transformation moves the pre - image onto the image?
reflection over the x - axis
reflection over the y - axis
translation 4 units down
none of the above

Explanation:

Step1: Analyze coordinate changes

For point C(5,2) and C'(5, - 2), x - coordinate remains 5, y - coordinate changes from 2 to - 2. For point A(-1,8) and A'(-1,-8), x - coordinate remains - 1, y - coordinate changes from 8 to - 8. For point T(1,0) and T'(1,0), y - coordinate is 0 for both pre - image and image. The general rule for reflection over the x - axis is (x,y)→(x, - y).

Answer:

Reflection over the x - axis
