Question

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

-12

-8

-6

-2

Answer 1

Answer:

  -6

Step-by-step explanation:

The y-coordinate of B is 2. Adding -8 to it makes the y-coordinate of B' be -6.

  2 -8 = -6

Answer 2

Answer:

-6

Step-by-step explanation:

The given translation is

$T_{-3,-8} (x,y)$

Which means that the original figure will be moved 3 units to the right and 8 units downwards.

Remember, when it comes to translations, when we subtract units to $x$ that means the figure will be moved rightwards. And if we subtract units from $y$, that means the figure will be moved downwards.

So, the original figure has as vertex B(1,2). If we apply the transformation to its vertical cordinate $y=2$, we would have

$y'=2-8=-6$

Therefore, the right answer is the third choice -6.
