Question

On a coordinate plane, a square has points A (negative 5, 2), B (1, 2), C (negative 4, 1), and D (negative 5, negative 4). If a translation of is applied to square ABCD, what is the y-coordinate of B'?

Answer 1

-2

Explanation:

Answer 2

The y coordinates of B' is: 8

Explanation:

Given

`A = (-5,2)`

`B =(1,2)`

`C = (-4,1)`

`D = (-5,-4)`

Translation of (x, y) → (x + 6, y – 10) ---Missing from the question

Required

Determine the y coordinates of B'

We have:

(x, y) → (x + 6, y – 10)

And

`B =(1,2)`

So the translation from B to B' is:

`B (1,2) \to B'(1+6,2-10)`

`B (1,2) \to B'(7,-8)`

So, we have:

`B' = (7,-8)`

The y coordinates of B' is: 8
