Math Problem Statement

Translate a point (x, y) 3 units left and 5 units up. Then translate the image 5 units right and 2 units up. What are the coordinates of the point after the translations?

Solution

To solve this problem, let's analyze each translation step-by-step.

  1. Initial Translation:

    • Starting point: (x,y)(x, y).
    • The point is translated 3 units left and 5 units up.
    • Moving 3 units left means we subtract 3 from the xx-coordinate: x3x - 3.
    • Moving 5 units up means we add 5 to the yy-coordinate: y+5y + 5.
    • New coordinates after the first translation: (x3,y+5)(x - 3, y + 5).
  2. Second Translation:

    • Starting from the new point (x3,y+5)(x - 3, y + 5), we translate 5 units right and 2 units up.
    • Moving 5 units right means we add 5 to the xx-coordinate: (x3)+5=x+2(x - 3) + 5 = x + 2.
    • Moving 2 units up means we add 2 to the yy-coordinate: (y+5)+2=y+7(y + 5) + 2 = y + 7.
    • Final coordinates after both translations: (x+2,y+7)(x + 2, y + 7).

Answer:

The coordinates of the point after the translations are: (x+2,y+7)(x + 2, y + 7)

Would you like more details on this solution or have further questions?

Here are some related questions for deeper understanding:

  1. How would the coordinates change if the initial translation were 5 units left instead?
  2. What would happen if the translations were applied in a different order?
  3. How would you represent these translations using vector addition?
  4. Can you describe this translation process using a matrix?
  5. What are other common transformations besides translations?

Tip: Translating a point in a coordinate plane involves adding or subtracting from the x- and y-coordinates based on direction.
