Math Problem Statement
What is the image point of left parenthesis, 0, comma, 7, right parenthesis(0,7) after the transformation T, start subscript, 3, comma, 0, end subscript, circle, r, start subscript, y, equals, minus, x, end subscriptT 3,0 ∘r y=−x ?
Solution
To find the image point of after the transformation , let's break down the process step by step.
Step 1: Apply the reflection
The transformation reflects a point across the line . The rule for this reflection is: So, applying this reflection to the point , we get:
Step 2: Apply the translation
The translation moves a point 3 units to the right and 0 units up. The rule for this transformation is: So, applying this translation to the point , we get:
Final Answer:
The image point of after the transformation is .
