Math Problem Statement

Point [B'(6,-5)] is the image of [B(-5,-2)] under a translation. Determine the translation. Use non-negative numbers.

Solution

To determine the translation, we need to find how the point B(5,2)B(-5, -2) is shifted to become B(6,5)B'(6, -5).

A translation moves a point by adding a fixed amount to both the xx- and yy-coordinates. The translation vector (a,b)(a, b) can be found as:

a=xxa = x' - x b=yyb = y' - y

Where:

  • (x,y)(x, y) is the original point B(5,2)B(-5, -2),
  • (x,y)(x', y') is the image point B(6,5)B'(6, -5).

Step 1: Calculate the change in the xx-coordinate:

a=6(5)=6+5=11a = 6 - (-5) = 6 + 5 = 11

Step 2: Calculate the change in the yy-coordinate:

b=5(2)=5+2=3b = -5 - (-2) = -5 + 2 = -3

Thus, the translation is by the vector (11,3)(11, 3).

The translation that maps B(5,2)B(-5, -2) to B(6,5)B'(6, -5) is (11,3)(11, 3).
