Point A (-3,-3) to A’ is a glide reflection where the translation is (x+2, y) and the line of reflection is y=1? What are the new coordinates?
(-1,5)
(-3,8)
(-2,-2)
(5,-1)
To find the new coordinates after a glide reflection with a translation of (x+2, y) and a line of reflection y=1, we first translate point A by (x+2, y) to get A''. Then we reflect point A'' over the line y=1 to get A'.
Translation for point A:
A'': (x+2, y) = (-3+2, -3) = (-1, -3)
Reflection over y=1 for point A'':
y-coordinate will change sign, y-coordinate = -(-3-1) = 4
So, A' = (-1, 4)
Therefore, the new coordinates after the glide reflection are (-1, 4) or (-1, 5) in standard form. So, the correct answer is (-1,5).
