If a translation of T–3, –8(x, y) is applied to square ABCD, what is the y-coordinate of B'?
The y-coordinate of is ______

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)
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)
