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 determine the coordinates of KK' and MM' after the translation, we follow these steps:

  1. Identify the original coordinates of KK and MM:

    • From the graph:
      • KK is at (4,1)(4,1).
      • MM is at (2,1)(2,-1).
  2. Apply the translation vector (6,2)(-6,2):

    • Translation means shifting each point by adding the vector components: (x,y)=(x+(6),y+2)(x', y') = (x + (-6), y + 2)
  3. Calculate new coordinates:

    • For KK': K=(46,1+2)=(2,3)K' = (4 - 6, 1 + 2) = (-2,3)
    • For MM': M=(26,1+2)=(4,1)M' = (2 - 6, -1 + 2) = (-4,1)

Final Answer:

a) The coordinates of KK' are (-2,3).
b) The coordinates of MM' are (-4,1).

Tip: A translation moves a shape without changing its size, shape, or orientation—just shifts it in the plane. 🚀
