Rectangle 1 has points (negative 4, 6), (negative 4, 4), (negative 1, 4), (negative 1, 6). Rectangle 2 has points (0, 0), (negative 2, 0), (negative 2, 3), (0, 3). Rectangle 3 has points (negative 2, 0), (negative 4, 0), (negative 2, negative 3), (negative (4, negative 3). Rectangle 4 has points (1, 0), (4, 0), (1, 2), (4, 2). Which rectangle shows the final image?

Solution

The transformation rule provided is T1, -4 CompositionRO, 180°(x, y). This rule combines two operations:

  1. Translation (T1, -4): This means the rectangle is translated (shifted) 1 unit to the right and 4 units down.
  2. Rotation (RO, 180°): This means the rectangle is rotated by 180 degrees around the origin (0, 0), which effectively flips it both horizontally and vertically.

Step 1: Apply the Translation (T1, -4)

The original rectangle KLMN has vertices at:

  • K(3,4)K(3, -4)
  • L(3,1)L(3, -1)
  • M(5,1)M(5, -1)
  • N(5,4)N(5, -4)

Applying the translation T(1,4)T(1, -4), we add 1 to the x-coordinates and subtract 4 from the y-coordinates:

  • New K(3+1,44)=(4,8)K(3+1, -4-4) = (4, -8)
  • New L(3+1,14)=(4,5)L(3+1, -1-4) = (4, -5)
  • New M(5+1,14)=(6,5)M(5+1, -1-4) = (6, -5)
  • New N(5+1,44)=(6,8)N(5+1, -4-4) = (6, -8)

So, after the translation, the new vertices are: (4,8)(4, -8), (4,5)(4, -5), (6,5)(6, -5), and (6,8)(6, -8).

Step 2: Apply the 180° Rotation

The 180° rotation around the origin transforms the point (x,y)(x, y) into (x,y)(-x, -y). Applying this to each of the translated points:

  • Rotate (4,8)(4, -8) to (4,8)(-4, 8)
  • Rotate (4,5)(4, -5) to (4,5)(-4, 5)
  • Rotate (6,5)(6, -5) to (6,5)(-6, 5)
  • Rotate (6,8)(6, -8) to (6,8)(-6, 8)

So, the final vertices after the 180° rotation are (4,8)(-4, 8), (4,5)(-4, 5), (6,5)(-6, 5), and (6,8)(-6, 8).

Step 3: Compare with Given Rectangles

Now, we compare these final coordinates with the given rectangles:

  • Rectangle 1 has vertices at (4,6),(4,4),(1,4),(1,6)(-4, 6), (-4, 4), (-1, 4), (-1, 6). This does not match.
  • Rectangle 2 has vertices at (0,0),(2,0),(2,3),(0,3)(0, 0), (-2, 0), (-2, 3), (0, 3). This does not match.
  • Rectangle 3 has vertices at (2,0),(4,0),(2,3),(4,3)(-2, 0), (-4, 0), (-2, -3), (-4, -3). This does not match.
  • Rectangle 4 has vertices at (1,0),(4,0),(1,2),(4,2)(1, 0), (4, 0), (1, 2), (4, 2). This does not match either.

Since none of the given rectangles match the final transformed coordinates (4,8),(4,5),(6,5),(6,8)(-4, 8), (-4, 5), (-6, 5), (-6, 8), it appears there may be a misunderstanding or discrepancy in the problem description or a mislabeling of the options. However, based on the transformation procedure, the correct final image should be found by visually matching this shape with the options provided.
