(5, -2) → (?, ?)
Multi-Step Transformation: Applying multiple transformations sequentially to a point
- Step 1: Apply x-axis reflection: (x, y) → (x, -y)
- Step 2: Apply translation: subtract 3 from x, add 4 to y
- Step 3: Calculate final coordinates
- Step 4: Verify result
P(5, -2) is in fourth quadrant
(5, -2) → (5, -(-2)) = (5, 2)
Move 3 units left: x = 5 - 3 = 2
Move 4 units up: y = 2 + 4 = 6
Final coordinates: (2, 6)
After reflection and translation, the point is at coordinates (2, 6)
• X-Axis Reflection: (x, y) → (x, -y) - y-coordinate changes sign
• Translation: Add/subtract fixed values to coordinates
• Sequential Application: Apply transformations in given order
A(1,3) → A'(?), B(-2,4) → B'(?), C(0,-1) → C'(?)
Origin Reflection: A transformation where every point (x, y) becomes (-x, -y)
A(1, 3) → A'(-1, -3)
B(-2, 4) → B'(-(-2), -4) = B'(2, -4)
C(0, -1) → C'(-0, -(-1)) = C'(0, 1)
A'(-1, -3), B'(2, -4), C'(0, 1)
The reflected triangle has vertices A'(-1, -3), B'(2, -4), and C'(0, 1)
• Origin Reflection: (x, y) → (-x, -y) for each vertex
• Triangle Properties: Shape and size remain unchanged
• Coordinate Sign Changes: Both coordinates change signs
(-3, 2) → (?, ?)
Rotation 90° CCW: Point (x, y) becomes (-y, x)
D(-3, 2) → D'(-2, -3)
D'(-2, -3) → D''(-(-2), -3) = D''(2, -3)
Point D''(2, -3) is in fourth quadrant
Final coordinates: (2, -3)
After rotation and reflection, the point is at coordinates (2, -3)
• 90° Rotation: (x, y) → (-y, x) - switch coordinates, negate new y
• Y-Axis Reflection: (x, y) → (-x, y) - x-coordinate changes sign
• Sequential Transformations: Apply in order specified
- Read Carefully: Identify all transformations required
- Sequence Planning: Determine order of operations
- Apply Step-by-Step: Execute each transformation systematically
- Verify Intermediate Steps: Check each transformation
- Confirm Final Answer: Validate with coordinate rules
- Document Process: Show work for review and learning
