Set 98
- After transforming point W, the new point will be named W'.
- False.Only some types of transformations change the size of an object.
- False.Reflections result in mirror images, but translations do not.
- False.Reflections most commonly are over the x-axis or y-axis,
but points or figures can be reflected over diagonal lines as well. - R' would have the coordinate pair ((x+h), (y+k))
Set 99
- N'(–3,–7)
- M'(–6,–1)
- L'((2 + –3), (–5 + –4)) = L'(–1, –9)
- D'(5, 2) and D''(–5, 2)
- T7,2. Since I is (7,2), I' would be (–7,2) after a reflection over the
y-axis. I''would be (–7,–2) after (–7,2) is reflected over the x-axis.
In order to navigate (–7,–2) to the origin, the translation T7, 2is
necessary. - (6,3).Since you are given V'' as (0,–1), reverse the operations of
the translation of T–6, 2in order to find V': ((0+6), (–1 – 2)) = (6,–3)
= V'. Since this was the image after a reflection over the x-axis,
V must equal (6,3).
