Question

Find the coordinates of the vertices of each figure after the given transformation. (1 points) Translate 4 units up.
Preimage D (-1, 4) E (-5, 2) C (-3, 0)
Image D', E', C'

Answer 1

To translate a point upward by a certain number of units, you add that number to the y-coordinate of each point.

For the given points D, E, and C:

1. **Point D (-1, 4)**:
- New coordinates: \((-1, 4 + 4) = (-1, 8)\)
- Image: D' = (-1, 8)

2. **Point E (-5, 2)**:
- New coordinates: \((-5, 2 + 4) = (-5, 6)\)
- Image: E' = (-5, 6)

3. **Point C (-3, 0)**:
- New coordinates: \((-3, 0 + 4) = (-3, 4)\)
- Image: C' = (-3, 4)

So the coordinates of the vertices after translating 4 units up are:
- D' = (-1, 8)
- E' = (-5, 6)
- C' = (-3, 4)
