A translation of [tex]T_{(-3,-8)}(x, y)[/tex] follows the rule:

[tex](x,y)\mapsto (x-3,y-8).[/tex]

From the diagram you can see that point B has coordinates (1,2). According to the previous rule this point will transform in point B' wit hcoordinates (-2,-6), because

[tex](1,2)\mapsto (1-3,2-8)=(-2,-6).[/tex]

Answer: the y-coordinate is -6.

The y-coordinate of B using the translation rule is: (-2, -6)

Translation Rule

  • Translation rule tells us how many unit we are moving a point considering the position of a point on a coordinate plane.

Given the translation rule as T(-3, -8)(x, y), therefore, applying this to B(1, 2) would be:

(1 - 3, 2 - 8) => (-2, -6)

Therefore, the y-coordinate of B using the translation rule is: (-2, -6)
