Math Problem Statement

What is the image point of (-1, -7) after a translation left 4 units and up 2 units?

Solution

The problem asks for the image point of (1,7)(-1, -7) after a translation 4 units to the left and 2 units up.

Translation steps:

  1. Left by 4 units: Subtract 4 from the x-coordinate. 14=5-1 - 4 = -5

  2. Up by 2 units: Add 2 to the y-coordinate. 7+2=5-7 + 2 = -5

Image point:

The image point after the translation is (5,5)(-5, -5).

Would you like further details on how translations work or have any other questions? Here are some follow-up questions for deeper understanding:

  1. What are translations in geometry, and how do they affect points?
  2. How do translations differ from rotations and reflections?
  3. Can translations change the size or shape of a figure?
  4. How would the translation change if it was 4 units to the right instead?
  5. Can you find the translation rule for different geometric transformations?

Tip: In translations, the shape and size of figures do not change—only the position changes.
