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

Answer:

The y-coordinate of B' is 8

Answer 2

Answer:

The y coordinates of B' is: 8

Step-by-step 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
