Math Problem Statement

What is the image point of left parenthesis, 3, comma, minus, 4, right parenthesis(3,−4) after a translation left 2 units and up 5 units?

Solution

To find the image point after a translation, you need to apply the translation to each coordinate of the original point.

The original point is (3,4)(3, -4).

  1. Translation left 2 units: This means subtract 2 from the x-coordinate: x=32=1x' = 3 - 2 = 1

  2. Translation up 5 units: This means add 5 to the y-coordinate: y=4+5=1y' = -4 + 5 = 1

So, the image point after the translation is (1,1)(1, 1).

  2. How do you translate a point when given a vector instead of direction and magnitude?
  3. If a point (x,y)(x, y) is translated by (a,b)(a, b), what is the general formula for the new coordinates?
  4. What is the effect of translating a point by (x,y)(-x, -y)?
  5. How would you determine the original point if only the translation and image point are known?

Tip: In coordinate geometry, translations preserve the shape and size of geometric figures.
