Math Problem Statement

J'K'L'M' is a translation of JKLM by vector (-6, 2). a) What are the coordinates of K'? b) What are the coordinates of M'?

Solution

To find the coordinates of KK' and MM', we need to apply the translation vector (6,2)\left( -6, 2 \right) to the original coordinates of points KK and MM.

Step 1: Identify the original coordinates

From the graph:

  • Point KK is located at (4,1)(4, 1).
  • Point MM is located at (1,5)(1, -5).

Step 2: Apply the translation vector

The translation vector is (6,2)\left( -6, 2 \right), which means we subtract 6 from the xx-coordinate and add 2 to the yy-coordinate.

a) Finding the coordinates of KK':

  • Original coordinates of KK: (4,1)(4, 1).
  • Applying the translation: K=(46,1+2)=(2,3).K' = (4 - 6, 1 + 2) = (-2, 3).

b) Finding the coordinates of MM':

  • Original coordinates of MM: (1,5)(1, -5).
  • Applying the translation: M=(16,5+2)=(5,3).M' = (1 - 6, -5 + 2) = (-5, -3).

Final Answers:

  • The coordinates of KK' are (2,3)(-2, 3).
  • The coordinates of MM' are (5,3)(-5, -3).

  1. What would be the new coordinates if the translation vector were (3,4)(3, -4)?
  2. How would the shape of the figure change if the vector had a magnitude of 45\sqrt{45} in a different direction?
  3. How can we determine the translation vector given the original and translated coordinates of any two points?
  4. What is the effect of translating a shape by a vector with both positive components?

Tip:

Always double-check the direction of translation by noting if the vector components are positive or negative, which indicates movement along the respective axes.
