Question

Triangle ABC is translated according to the rule (x, y) → (x + 2, y – 8). If the coordinates of the pre-image of point B are

(4, –5), what are the coordinates of B'?

(2, 3)
(1, –9)
(–3, –4)
(6, –13)

Answer 1

(6, –13)

Explanation:

The answer above is correct.

Answer 2

(6,-13)​

Explanation:

substitute x=4 and y=-5.

Therefore,

B(4, -5 ) → B(4+2,-5-8)

Simplify

B(4,-5) → (6,-13)​

or you can do:

(4, -5) ⇒ (4+2, -5-8) = (6, -13)
