Pre-Algebra – Unit 6 – Combinations of Transformations Day 2
For each set of pre-image coordinates below, give the set of image coordinates for each transformation.
Then, give the image coordinates after performing the second transformation.
Rotation: 270 degrees counterclockwise
Rotation: 90 degrees counterclockwise
Dilation k = 4
Rotation: 180 degrees
Translation (𝒙, 𝒚) → (𝒙 + 𝟏𝟎, 𝒚)
Rotation: 270 degrees counterclockwise
Reflection: x-axis
Reflection: y-axis
Translation (𝒙, 𝒚) → (𝒙 + 𝟑, 𝒚 − 𝟕)
Dilation k = 2
Reflection: x-axis
Translation (𝒙, 𝒚) → (𝒙 − 𝟑, 𝒚)
Translation (𝒙, 𝒚) → (𝒙, 𝒚 − 𝟕)
Dilation: 𝒌 = 𝟏𝟐
Reflection: y-axis
Translation (𝒙, 𝒚) → (𝒙 + 𝟑, 𝒚)
Solve each equation. Show any work that leads to your answer.
2𝑥 + 9𝑥 = 33
5𝑥 + 14 − 12𝑥 = 49
3(𝑥 − 6) + 2𝑥 = 32
